Steve Waugh shot past another milestone as he scored a century against Bangladesh to complete his set against every Test cricket side in the world.

His 31st Test century in his 250th Test innings helped propel the Australians to a commanding position, and signalled the skipper had relaxed after the rigours of having to prove his worth after a lean period following the 2001 Ashes tour.

Waugh's ton - off 133 balls, including 10 fours and a huge six - sparked the declaration from the Australian camp, at 7-407.

Bangladesh, bowled out for 97 first time around, fought back bravely late in the day, smashing Australia's bowlers around the field to be 1-70 from 15 overs late in the day. But they still require a daunting 240 runs just to stay in the match.

"If you play long enough you are going to reach some milestones and records are going to be past, and I'm sure someone down the track will beat those," Waugh said.

"But it is nice to achieve things and to score 100 against every country is something I'm proud of.

"I just set myself to play well and to enjoy it and be positive and I think I've done it over the last 12 months, that's probably why it's more pleasing."

South Australian Darren Lehman was the first player to score a Test century at Marrara Oval, his knock coming off 208 balls.

Lehmann, who seemed the most comfortable of the Australians, reached a total 110 before he was caught in the deep by Javed Omar when hitting out against Mashrafe Mortaza.

Waugh said he had been able to relax away from the big smoke, enjoying his trip to northern Australia with his family.
