Title-favourites Brisbane suffered two crushing losses in a horror weekend on the road for Queensland's three NBL representatives.

The Sydney Kings' championship defence was also dealt an early setback, as the Wollongong Hawks and Perth Wildcats (both 2-0 win-loss records) emerged from the weekend as the only unbeaten teams after the second round of the season.

Nominated in many pre-season polls as the team to beat this year, the Bullets (1-2) lost 108-100 to Wollongong on Saturday night, before being pummelled 106-75 by West Sydney (1-1) at the Pigpen on Sunday.

Following the loss to the Razorbacks, Bullets coach Joey Wright said complacency had crept into his team.

"We have to start getting out there and smelling blood, we have not had that in the pre-season, maybe we needed that loss to get that back," Wright said.

Wollongong showed its lack of height wouldn't stop it being a title contender, as it claimed top spot on the ladder with the win.

The Hawks relied on their stingy defence and a stellar performance from Boomers small forward Glen Saville, who tallied 24 points, 15 rebounds and four blocks, in the 8-point win.

"We've just played the two teams (Melbourne and Brisbane) that have been predicted to finish as the top two, and we beat them both, so we know we're going to compete this year," Hawks coach Brendan Joyce said.

At the Sydney Olympic Park Sports Centre, the Bullets were simply awful, connecting on only 28 per cent of their field goal attempts in a 31-point hiding by the Razorbacks.

The worst offenders at the offensive end were Derek Rucker (1/6), Bobby Brannen (2/15) and Simon Kerle (2/10).
