The Opals won the 2006 world championship and are ranked number two in the world behind the Americans.

But the dual silver medallists don't need reminding that world number four Brazil have been one of their most formidable rivals over the past decade.

They met twice at the world titles two years ago. The Opals won their pool clash by 12 and knocked the South Americans out of the tournament with an 11-point victory in the semi-final.

Australia had Brazil's measure at a similar pre-Olympic tournament at WIN Entertainment Centre in 2000 and Jackson was confident this deeper and more talented Opals side would emulate that success.

"They're a good team and they deserve to be number four in the world, so we're not under-estimating them, but we feel confident we can win," Jackson said.

"Brazil nearly knocked us out of the world championship, so we're fully aware of what they can do. They've got great players and we've got a lot of talented players, world class players that would make any team in the Olympics.

"If Brazil wants to try and shut me down, fine, Penny Taylor will step up. If they shut Penny down, Suzy Batkovic will be there and Belinda Snell and Kristi Harrower and I could name every player on this team. We're a long way from a one-woman show."

The Opals have steadily built towards Beijing since their first training camp in May and were put through their paces in no uncertain terms with an intense boot camp last week.

Jackson believes the side's ability to stick together under pressure in close games will hold them in good stead throughout their Olympic campaign.

"Our chemistry is amazing and that's what gets us through the tough situations," she said.

"The Opals team that won the world championship had the best chemistry of any team I've ever been involved with and we've only made two changes to it since, so we're a tight, tight group."

Plenty of tickets are available for tonight's game.

An Albury junior, Jackson has fond memories of her junior playing days in Wollongong and is hoping the Wollongong community come out and give the Opals an Olympic-sized send-off.

"It's great to get back to Wollongong," she said. "I played junior ball at the Snakepit and hopefully the entertainment centre will be packed and supporting the Opals. It should be a great night."

Both teams will be at full strength. Tip-off is at 7pm.
