In the wake of the chaotic Albert Park race last season, which witnessed four red flags, race organisers were found guilty of breaching FIA security protocols when fans invaded the track while cars were still running.
As well as the clear safety implications of potentially being hit, fans were also able to reach the stranded Haas of Nico Hulkenberg.
The car had parked on the exit of Turn 2 after finishing seventh and had its flashing red warning light activated, signalling it was in an unsafe condition with potential electrical discharge.
Event organisers were asked to come up with a remedial plan after race stewards declared: "The security measures and the protocols which were expected to be in place for the Event were not enforced resulting in an unsafe environment for the spectators, drivers and race officials."
It was not the first time that fans had invaded the Melbourne track in such a manner, with similar problems having blighted the 2017 event, and the situation was due to be looked at by the FIA's World Motor Sport Council.
But with the matter still ongoing between organisers and the FIA, a decision has been taken to impose a total clampdown on any fan access to the circuit after this year's grand prix.
This marks an end to a long tradition where Melbourne fans have rushed onto the track in time to join the podium celebrations.
