She was to represent trainer Paul Nairn in the series had she gained a start and that is still a possibility as she only needs one horse to pull out to gain a starting spot.
The scenario has led to Nairn and owner Richard Cornelius working on a secondary plan in case that does not happen.
"She only needs one to pull out in either of the heats," Nairn said.
"Richard has got a Plan B.
"The horse will still go over, even if she doesn't get in to the Inter Dominions."
"She will go to Tim Butt in Sydney and if she were to sneak into the field at the last minute he can still take her down there."
Wilma's Mate's last start fifth at Addington last Friday was enough to suggest she was worthy of an Inter Dominion tilt.
"She trotted a lot better so, hopefully we have got her right," Nairn said.
"I hope it is not just a one off, there has been a mix of things. A couple of her runs were a bit disappointing, but in saying that, she was coming back from a long spell
"And it is a tough grade to come back in."
"She has had a couple of checks that have not really been her fault, that have caused her to gallop," he said.
Wilma's Mate heads back to Australia with the hope she can keep her unbeaten record there intact.
She won the Victorian Trotting Derby and the Breeders Crown three-year-old fillies title, as well as a minor race, in the winter of 2016.
Whether she makes it to the Inter Dominion in Nairn or Butt's colours will decide if three
or four trotters fly the New Zealand flag in the series.
Speeding Spur has been ranked the number one trotter in the series after yesterday's final rankings.
Trainer Phil Williamson's pair of Monty Python and Alderbeck are ranked ninth and 11th, respectively.
The release of the final rankings for the Interdominion pacing series confirmed just three New Zealand pacers are set to head to Melbourne.
All Stars pacer Cruz Bromac is the number two ranked horse in the series behind Tiger Tara, while Spankem sits in 15th spot, one higher than Pat's Delight, who is in 16th.
