Melbourne cricket fans could flock to two Ashes Test matches this summer, with the prospect of gaining the fifth and final clash from Perth gaining momentum and potentially being held under lights.

Both Sydney and Melbourne have been flagged as the frontrunners to replace the Western Australia Test should state border restrictions continue to hinder the cricket calendar.

While Canberra and Tasmania are also hopeful of being handed the hosting rights for the summer's final Test, both the MCG and SCG are seen as more enticing suitors.

Melbournians have already begun securing seating for the Boxing Day Test after tickets went on sale on Monday, with further record crowds expected after a year heavily impacted by the COVID-19 virus.

Victorians could be handed a double delight should the Perth Test - scheduled to commence on January 14 - be moved to the MCG, with The Sydney Morning Herald reporting the added fixture could be held as a day-night match.

The concept would see the second instalment of the Melbourne Test join its Adelaide counterpart in being held under lights, with the Ashes tour agreement stating no limitations on the number of day-night matches.

A pink ball Test would also accommodate the missed spectacle for Western Australians, with an afternoon start suitably aligning with the state's timezone.

The MCC have been proactive in their bid to replace the Perth Test should a call be required, with club chief executive Stuart Fox revealing to 3AW that the ground would be ready should Cricket Australia require the change.

“We've snuck another [pitch] in right beside it,” Fox said.

“We're never cheeky about these things because we've lost two grand finals and I don't like seeing other states pinch content. But we're ready if we're needed, and if Cricket Australia just accidentally made a phone call to us and said, ‘We need you to host a second Test,' we'd be ready to go."

A timeline for a decision on the fifth Test is yet to be flagged by CA, however with the opening match just eights days away, the critical could be made as early as next week.
