The Steel will go into the sudden-death ANZ Championship play-off match in Adelaide on Monday as the underdog but Grant says her side has every reason to believe it can register its first win in Australia.
The Steel outplayed the Thunderbirds in Dunedin two weeks ago and the nine-goal win has done wonders for the team's self-belief.
But what is of more significance, perhaps, is the fact there will be a New Zealand and an Australian umpire officiating in the game.
New Zealand teams have struggled with the interpretations of the Australian umpires and Grant believes a New Zealand whistle-blower at one end will even those odds.
"That might help change the tide and help us win over there," Grant said.
Of course, having two umpires who might interpret the rules differently poses its own set of issues.
"At one end you're going to get pinged and at the other end you're not going to get pinged at all."
Umpiring aside, the Steel will fall back on the game plan that worked so successfully in Dunedin: slow the Thunderbirds' ball down, cramp their shooters for space and stay patient on attack.
"We'll have to slow them down in the midcourt. That's what they're renowned for. We slowed them down in Dunedin and they could not get a roll on us.
"Home court advantage is huge, especially for the Aussies. But our confidence against Australian sides is really high at the moment so I don't see why we can't go over there and dominate them."
The combined Southland-Otago team started the season lukewarm but has made giant steps in the past three weeks.
The Steel had a narrow loss in Brisbane against the Firebirds but bounced back with impressive performances against the Thunderbirds and Swifts.
The Thunderbirds also look like they have hit their best form at the right time.
They smashed the Magic 54-35 in Adelaide last weekend.
"They'll be on a high after the Magic game but, if you look at it, we're a totally different team to the Magic.
Our attacking line-up is way different, so if we just play like we did in Dunedin we should be fine."
Grant is looking forward to renewing her rivalry with Thunderbirds goal attack Natalie Medhurst.
"She is such a classy player with her speed and accuracy. We had a good battle last time and hopefully I can get the better of her on Monday."
A good performance will not do Grant's international prospects any harm.
With the Silver Ferns squad expected to be named following the ANZ Championship, the selectors will be keeping a close eye on the progress of the Magic and Steel squads.
"It [national selection] is always in the back of your mind but you've just got to concentrate on one thing, and this semifinal is huge for us."
Steel defender Sheryl Scanlan will travel with the team but her calf injury is likely to prevent her from taking the court.
