Dhaka: Nathan Lyon passed Richie Benaud's mark of 248 wickets and went on to hit the 250 mark as Australia bowled out Bangladesh for 260 on day one of the first Test in Dhaka.
Lyon took 3-79 and the recalled Ashton Agar claimed 3-46 after Pat Cummins (3-63) began the day with a withering spell that included three wickets in eight balls at the Sher-E-Bangla Stadium.
A short time ago, Australia were 0-6 in reply, with David Warner (5no) and Matthew Renshaw (1no) at the crease.
Veteran Tigers pair Shakib Al Hasan (84) and Tamim Iqbal (71) steadied the ship through much of the first half of the day, the 155-run stand a much-needed one after Cummins left Bangladesh reeling at 3-10 off four overs.
Playing just his fourth Test in a hugely promising but injury-affected career, Cummins was a revelation despite the draining 75 per cent humidity in Dhaka.
The 24-year-old struck on his fifth ball, squaring up Soumya Sarker with a well-pitched delivery which was caught by Peter Handscomb at gully.
On a dry and dusty deck, Cummins still managed to trouble the Bangladeshi batsmen with his speed, finding the edge of Imrul Kayes for Matthew Wade to take a regulation catch in his second over.
Cummins and Wade combined again off the next ball to dismiss Sabbir Rahman for a duck. Sabbir called for a review but replays showed a thick edge, and Bangladesh fell to 3-10.
Cummins was unable to finish off the hat-trick but after winning the toss and electing to bat, it was a dreadful start for the hosts which was salvaged by Shakib and Tamim's aggressive fourth-wicket stand.
The all-time leading run scorers for Bangladesh, big-hitting opener Tamim and star allrounder Shakib were always going to be the danger men in the hosts' batting lineup.
The pair signalled their intent to go after Australia's spinners, with Tamim belting two sixes off the bowling of Lyon, who regularly beat the bat of the left-handers outside off stump.
The introduction of part-time offie Glenn Maxwell did the trick for captain Steve Smith, with the Victorian removing Tamim, who miss-hit a cut shot to David Warner at backward point.
Minutes before tea, Lyon was finally rewarded for his consistency, Shakib falling short of a hundred in his maiden innings against the Aussies when he edged an attempted cut to Smith at first slip.
The 29-year-old moved level with Benaud as Australia's second-most prolific slow bowler in Test history, before taking another two in the final session, during which Agar claimed three to knock over the hosts shortly before stumps.
