Bendigo Spirit coach Bernie Harrower said his side will not be underestimating giant-killers Townsville Fire when the two sides clash in the WNBL grand final at Bendigo Stadium on Sunday.

The Spirit head into the grand final warm favourites after claiming the 2012-13 minor premiership with a 21-3 regular season record.

Both sides are chasing maiden WNBL titles and both are in great form.

Bendigo produced a second-half fightback to win its major semi-final against defending champions Dandenong two weeks ago.

Townsville has produced a stunning run to knock over more fancied opponents Adelaide and Dandenong in consecutive weeks.

Harrower said he was not surprised to see Townsville claim those two big scalps.

"Sometimes if you underestimate teams you're ripe to get beaten," he said on Friday.

"This league is so even and so tough if don't come ready to play or you're off 10 per cent on the day, you can get beaten by any team in the competition."

It will be a family occasion on Sunday for the Harrowers with Bernie teaming with daughter Kristi, a four times Olympic representative.

She will be heavily marked by Townsville's Rachael Flanagan, perhaps the in-form guard of the competition.

Townsville coach Chris Lucas said he has no superstars in his team but the recent performances have come on the back of superb teamwork.

"The team chemistry right now is unbelievable," Lucas said at the grand final launch in Bendigo.

"They play not unlike Bendigo, they just play for each other.

"It's not about individuals. We don't have any superstars in our team and that's the bonus of our team that in any one game someone's going to step up."

ABC TV will broadcast live the grand final between Townsville and Bendigo in Queensland, NSW, Victoria and Tasmania from 3.30pm (AEDT).
