The Inter Dominion hosting rights go up for tender, with the winning state or club granted the series for three years.
Menangle's tenure runs out with the final next March and bids for the 2016-18 series close in Australia on Monday.
It is doubtful whether Victoria, which has the busiest carnival programme of any Australian state will bid for it, while NSW is not showing its hand.
Neither Addington nor Alexandra Park will bid for the hosting rights.
Gloucester Park in Perth will and has the backing of the WA State Government, via its racing board RAWA (Racing and Wagering WA).
If their bid is successful, and they would have to be a warm favourite at the moment, they will hold three rounds of heats, possibly with one or two of those rounds held at a track outside of Perth, most likely Pinjarra.
Then there would be a Friday night final, which has the potential to lure a huge crowd by modern-day harness racing standards, because Gloucester Park is located close to the CBD of Perth.
A return to the traditional Inter Dominion format will be popular with racing traditionalists and Perth bosses told the Herald yesterday if they are successful they will endeavour to make series participation as easy as possible for visitors.
That would include putting on free air transport for leading horses from the eastern states of Australia, where many Kiwi pacers will already be competing in races like the Victoria Cup.
Gloucester Park officials say if their bid is successful, they will entertain an earlier time slot for the final to accommodate harness racing fans in eastern states and New Zealand who may not be keen to stay up until, in the case of New Zealand, 1am to watch the series climax.
