Organisers have not said exactly how the event will work, but it is expected to follow a similar format to this year’s edition.
The professionals were allowed to serve once and the amateurs twice – as is the norm in traditional tennis.
While it is unclear how the draw will work, there will be five knockout rounds and the venue will be the Rod Laver Arena rather than the smaller Kia Arena.
The final stages will take place in a night session instead of 1pm local time.
Any Australians – or international players who have registered with Tennis Australia – can enter ‘One Point Slam’ events at their local tennis clubs.
The winners of the grassroots tournaments will then go into a draw, with one amateur player from every state and territory selected to take part in the ‘grand finale’ in a night session on Wednesday, 14 January.
There will also be a qualifying draw in December which amateurs, lower ranked pros, celebrities and sport stars can enter.
It starts on Monday, 12 January and the two winners will go into Wednesday’s ‘grand finale’ with the other eight amateurs and 10 professionals.
