Costco Marsden Park: Fuel Prices, Hours, Address Guide

If you’ve ever pulled into a Costco fuel station expecting routine prices, the pump display probably made you do a double-take. Members in Sydney’s western suburbs have been keeping a close eye on the Costco Marsden Park fuel prices precisely because they tend to undercut nearby competitors — but only if you know when to fill up. This guide cuts through the conflicting data so you can plan a trip that actually saves you money.

The table below consolidates essential contact and location details sourced from official Costco records and verified fuel trackers.

How much is Costco Petrol Marsden Park?

The figure you’ll see on the pump sign depends entirely on when you last checked — prices move fast. According to fuel price trackers, recent Costco Marsden Park rates reportedly included Unleaded E10 ranging from roughly 152.7¢ per litre up to 242.7¢ per litre depending on the reporting date (Petrol Spy). That kind of variance isn’t unusual across Australian fuel stations, but Costco members have learned to time their fills strategically.

“Prices shown here are updated frequently, but may not reflect the price at the pump at the time of purchase. All sales will be made at the price posted on the pumps.”

Current fuel prices

Tracker data from mid-July showed E10 at 152.7¢ (down 0.7%), Premium Diesel at 165.7¢ (up 1.2%), and Premium 98 at 172.7¢ (down 1.7%) (FuelRadar Australia). However, prices shown on Costco’s own site are marked as indicative and may not reflect the pump price at the time of purchase — what gets charged is what posts at the pumps (Costco Australia). AdBlue, consistently listed at around 122.0¢, tends to be among the cheapest available at this location (Petrol Spy).

Comparison with nearby stations

Costco fuel stations typically undercut surrounding servo prices by 5–15¢ per litre when prices are aligned. The key variable is the daily wholesale cycle — Costco often hits its lowest point mid-week (Tuesday–Thursday) while nearby competitors may still be cycling through weekend highs.

The catch: you’ll need an active Costco membership to access the bowser. Non-members are turned away, so the savings only materialise for those already paying the annual fee (FuelRadar Australia).

What’s the best time to visit Costco Marsden Park?

Timing your warehouse visit correctly can mean the difference between a smooth run and a 45-minute queue snaking around the car park. The Marsden Park location draws from a wide catchment — residents of Quakers Hill, Riverstone, Schofields, and beyond all converge here — and that traffic follows predictable patterns.

Avoiding crowds

The quietest windows are mid-morning on weekdays, roughly 10:30 AM to 12:30 PM, after the early rush clears and before the post-lunch pickup begins. Tuesday and Wednesday mornings are typically the lightest trading days for NSW Costco warehouses including Marsden Park (Costco Australia). Saturday mornings, by contrast, tend to be the busiest — the weekend crowd peaks between 9:00 AM and 11:00 AM.

• Best windows: Tuesday–Wednesday 10:30 AM–12:30 PM
• Quietest fuel access: Weekday mornings (6:00 AM opens) before 7:30 AM
• Avoid: Saturday 9:00–11:00 AM; Sunday early afternoon

Weekday vs weekend

Weekday evenings (after 6:00 PM) can be surprisingly manageable on Thursday and Friday, with traffic thinning once workers heading home have passed through. Sunday has its own rhythm — the 10:00 AM opening draw means a predictable queue by 10:15 AM, which typically clears by noon. If you’re heading to the tire centre or pharmacy, weekday afternoons after 2:00 PM generally offer the shortest waits.

For fuel specifically, the extended station hours (Mon–Fri 6:00 AM–9:30 PM, Sat 6:00 AM–7:30 PM, Sun 7:00 AM–7:00 PM) mean you can often skip the warehouse crowd entirely and hit the bowser during a quiet pocket in the evening (Costco Australia).

The trade-off: Saturday shopping convenience is tempting, but the time cost of queuing often outweighs the fuel savings. For regular members, midweek runs become a habit.

“Over the past 14 days at this station, prices have shown mixed movements.”

What are the Costco Marsden Park opening hours?

The warehouse and fuel station run on separate schedules — a distinction that catches many first-time visitors off guard. Costco Australia lists different windows for the main store versus the fuel station, and both are relevant depending on what you’re there to do.

Weekday hours

The Marsden Park warehouse operates Monday through Thursday from 10:00 AM to 8:30 PM, with Friday also closing at 8:30 PM (Costco Australia). The fuel station, by contrast, kicks off at 6:00 AM and runs until 9:30 PM on weekdays — a full four hours earlier in the morning and an hour later at night than the warehouse itself (Costco Australia). In-store services including the pharmacy, tire centre, optometry, and hearing aid centre follow the warehouse schedule, not the fuel station schedule.

Weekend and holiday hours

Saturdays the warehouse opens at 9:30 AM and closes at 6:30 PM, while Sundays see reduced hours of 10:00 AM to 6:00 PM (Costco Australia). The fuel station Saturday hours run 6:00 AM to 7:30 PM, with Sunday bowing to 7:00 AM to 7:00 PM. On public holidays, the warehouse and in-store services typically close, so it’s worth checking the NSW warehouse holiday schedule before heading out (Costco Australia).

The pattern: Marsden Park follows the same standardised NSW warehouse hours as other locations including Crossroads, Lake Macquarie, and Auburn (Costco Australia). If you’re familiar with any NSW Costco, the rhythm will feel familiar — but the fuel station’s extended morning window is unique to those who need an early fill.

What is the Costco Marsden Park address and contact info?

Getting directions right matters more than you might think — there’s an address discrepancy between the official warehouse listing and the fuel station location that has confused members for some time.

Full address and directions

The official Costco Marsden Park warehouse address is 10 Langford Drive, Marsden Park, NSW 2765, confirmed on Costco Australia’s store finder and backed by multiple verification sources (Costco Australia). Fuel price trackers, however, list the station as 43 Hollinsworth Road, Marsden Park NSW 2765 (Petrol Spy). This split-address situation is common in Australian retail where the fuel station occupies a separate entry point from the main warehouse building. If you’re using GPS, search for the warehouse address first — the fuel station entrance is typically signposted from the same site.

Phone and email

The primary phone number for the Marsden Park warehouse is (02) 9854 3700, verified across official Costco Australia records and fuel tracker listings (Costco Australia). Additional service extensions reportedly listed include 3780, 3731, and 3770 for various departments. For general enquiries, email marsdenpark@costco.com.au is the direct contact listed on the official site (Costco Australia).

The implication: always confirm the entry point before your first visit — warehouse and fuel station entrances may use different street addresses, but both are on the same Costco property in Marsden Park.

Can I enter Costco Marsden Park without a membership?

The short answer is no — but there are nuances worth understanding before you drive across Sydney’s west hoping for a loophole.

One-day pass options

Costco Australia does not offer a standard one-day visitor pass for non-members. The membership requirement is enforced at the entry door, not just at checkout. Unlike some warehouse models in other markets, Australian Costco enforces membership at point of entry for all shopping visits.

Guest entry rules

Members can bring up to two guests per visit, provided the member is present and will be making the purchase. The guest entry is intended for members to show the warehouse to potential new members — not as a workaround for non-members wanting to shop. Fuel purchases follow the same membership requirement: the card must be scanned at the bowser (FuelRadar Australia).

Current Costco Australia membership fees start at approximately $60 annually for Gold Star membership, with Executive membership available at a higher tier offering a 2% reward on qualifying purchases (Costco Australia). For fuel-only buyers, the annual fee typically pays for itself after roughly $600–$800 in fuel savings at Costco’s price differential — a threshold Sydney-area drivers often reach within three to four months of regular filling.

The catch: if you’re only after the fuel savings and not the bulk shopping experience, the membership math still works — but you’ll need to commit to filling up consistently to justify the cost.

Frequently asked questions

For Sydney’s western-suburbs drivers, the value proposition is straightforward: a Costco membership turns the trip to Marsden Park into a two-for-one deal. You fill the tank at prices that undercut surrounding stations, then grab the weekly shop in bulk — the $60 annual fee pays out in fuel savings before you’ve finished loading the boot. The key is checking a live fuel tracker before you drive. Prices that look great mid-week may have cycled to a high by Saturday morning, and the difference on a 60-litre tank can erase most of your membership cost in a single fill. Plan around the tracker, and Marsden Park becomes one of Sydney’s most reliable money-saving stops.
