With the exception of Brazil, Great Britain have already faced all of their opponents this summer, including Australia, who will be the opening opponents on Saturday evening.
The two sides met in Sheffield a fortnight ago and although the Opals won 87-63, Great Britain acquitted themselves well and will be looking forward to the re-match.
Leading scorer Jo Leedham recently competed in the Australian WNBL league with Bulleen Boomers, playing for coach Maher, and will have seen plenty of the Australian players in action.
"I've played against a bunch of them," she said. "It's great that we already have a feel for their players and what they can do, we know what to expect. I was fortunate that I had three of them on my team last year so I know them pretty well."
Next up will be Canada, who booked their place in London via the Olympic Qualifying Tournament in Turkey and when the sides met in Edinburgh earlier this summer, the teams split the two-game series.
After that GB face Russia, a game Great Britain have been looking forward to since last year's EuroBasket when they almost upset the eventual champions.
If their last meeting was anything to go by, then the penultimate group game against France will be eagerly anticipated. Two weeks ago Great Britain put in their best performance of the summer as they defeated the French 74-67.
The final group game will see GB going up against Brazil, who booked their place in London after winning the 2011 Tournament of the Americas, and GB will want to end on a high ahead of a possible qualification for the knockout stages.
"This is going to be possibly the greatest Olympics of all time," commented Maher. "I'm sure the warm-up games have given the players self-belief that we can compete.
"There is a way, we have a path. We can follow that path and be successful."
