Melbourne Petrol Prices Show 40 Cent Gap as Tarneit Surges While Coburg Drops
*12th December 2025 2:45pm AEDT*
A closer look at today's Melbourne petrol prices reveals a striking 40 cent disparity between neighbouring regions that deserves attention from motorists across the city. While Tarneit in the western growth corridor has seen unleaded prices surge over 23 cents to average 190.2 cents per litre, Coburg in the north has dropped nearly 18 cents to sit at 182.2 cents.
This raises some interesting questions about what's driving such vastly different outcomes in suburbs separated by just 25 kilometres.
The Western Suburbs Price Surge
Motorwrists in Melbourne's outer west are copping significant price increases this week. Tarneit servos have jumped from 166.9 cents to 190.2 cents for standard unleaded, a staggering 23.3 cent increase that's adding roughly $12 to a 50 litre tank.
Premium 98 in Tarneit has followed suit, climbing 30.8 cents to reach 212.7 cents per litre. For motorists running performance vehicles in the area, that's an extra $15 per fill up compared to just days ago.
Digging deeper into the numbers, the western growth corridor appears to be experiencing the sharp end of Melbourne's fuel price cycle. Nearby suburbs including St Albans and Taylors Lakes are showing similarly elevated pricing, though St Albans has seen some relief on premium 98, dropping substantially from inflated levels.
Northern Relief Provides Alternative
Meanwhile, motorists in Coburg and surrounds are enjoying the opposite conditions. Unleaded has dropped from 199.9 cents to 182.2 cents, a decrease of 17.7 cents that makes the trip north well worth considering for western suburbs drivers.
Preston nearby is also showing favourable conditions, with E10 prices down 8.3 cents to average 177.6 cents. For E10 compatible vehicles, that represents genuine savings of around $4 per tank compared to standard unleaded at inflated western prices.
The pattern extends across Melbourne's northern suburbs. Epping diesel has dropped 8.3 cents to 191.6 cents, while Reservoir continues to offer competitive diesel at 178.7 cents average.
Regional Victoria Comparisons
Beyond the metro divide, regional Victoria presents its own mixed picture. Ballarat has seen diesel climb 12.3 cents to 189.3 cents, with premium 98 following a similar upward trajectory.
However, Moe in Gippsland stands out as a regional standout, with diesel averaging just 174 cents and a minimum of 166.5 cents at competitive stations. Bright in the alpine region is also holding steady with diesel averaging 174.2 cents.
The Gippsland corridor appears to be resisting the price increases affecting other regions. Traralgon diesel has climbed 8.6 cents but remains competitive at 186 cents average.
What This Means for Melbourne Motorists
The current pricing pattern reveals several opportunities for informed consumers:
Northern suburbs currently offer the best value for both unleaded and E10, with Coburg, Preston, and Reservoir all showing prices 10 to 15 cents below western alternatives.
Western corridor drivers may benefit from timing purchases carefully. The sharp surge suggests these areas have entered the high point of the price cycle, and relief typically follows within days.
Diesel users should note that Epping and Deer Park offer sub-180 cent pricing, competitive even against regional alternatives.
Price Transparency Matters
The 40 cent gap between Melbourne suburbs on the same day highlights why checking prices before filling up can save considerable money over time. A motorist filling up weekly in Tarneit at current prices versus Coburg would pay an extra $20 per week, or over $1,000 annually.
These variations between neighbouring areas are worth investigating. While location convenience matters, the data suggests that even a short detour to competitive suburbs can deliver meaningful savings.
Armed with this information, Melbourne motorists can make informed decisions about when and where to fill up. The cycle will inevitably turn, but today's winners are clearly in the northern suburbs.
