Australia, reeling early on at 28 for three, were 237 for four at the close in reply to Pakistan's first innings score of 269. Slater, who hit 108, and Waugh, who ended the day on 104 not out, shared a resolute fourth-wicket partnership of 198 runs in 246 minutes.

They came together in the morning session after pace bowler Wasim Akram had claimed the wickets of captain Mark Taylor and Justin Langer in successive deliveries and leg-spinner Mushtaq Ahmed had dismissed Mark Waugh for nought.

Slater was out playing a tired shot, caught at cover by Mohammad Wasim off left-arm spinner Mohammad Hussain after tea.

He hit 11 fours and a six off Mushtaq in his eighth Test century. His hundred came in 238 minutes and 205 balls and his innings lasted 298 minutes.

Waugh's hundred, his 15th in Tests, came half an hour later in 256minutes and 220 balls, with nine fours and a six off Saqlain Mushtaq.

The Pakistan bowlers did beat the bat on quite a number of occasions but had no luck as Slater and Waugh mixed caution with aggression to thwart them.

``It was highly satisfying to make a hundred in the first Test against Pakistan,'' said a delighted Slater, whose last last century was 219 against Sri Lanka in 1995-96 in Australia. ``It was tough but enjoyable,'' Waugh said.

Saeed Anwar and Mushtaq resumed the Pakistan innings in the morning at 253 for eight, having rescued their side yesterday with a record ninth-wicket stand for Pakistan in Tests against Australia.

But the last two wickets fell for only 16 more runs just 50 minutes into the session.

Opener Anwar, 132 overnight, was caught by Langer at short leg off leg-spinner Stuart MaCgill for 145, having hit 12 fours and batted for 386 minutes. The ninth-wicket stand was finally worth 120.

MaCgill finished with five for 66, his second Test haul of five wickets since he madehis debut earlier this year.
