Shoriful Islam took particular satisfaction from dismissing Pat Cummins with a bouncer of his own on Saturday, after the Australian captain had earlier struck him with a bouncer of his own.

"It felt good," Shoriful said with a smile. "Because he had hit me on the shoulder with a bouncer."

Yet despite the six wicket return, Shoriful insisted a Bangladesh win would mean far more to him.

"The feeling is obviously good. First of all, I thank Allah," he said. "Right now, I am not thinking that I am very happy because I have taken five wickets. If we win the match, then I will be very happy."

Bangladesh were bowled out for just 64 in the second Test at Mackay, but Shoriful's brilliant burst with the ball gave the tourists hope of a fightback, as his six wickets left Australia struggling for control on the opening day.

Returning from the hamstring injury that ruled him out of the Darwin Test, the left-arm pacer wasted no time making an impact. He removed Travis Head and Marnus Labuschagne inside his very first over, leaving Australia reeling at 41 for three.

Steven Smith and Cameron Green then added 77 together to steady the innings, only for Shoriful to strike again, trapping Smith lbw for 42. Mehidy Hasan Miraz chipped in too, removing Alex Carey for just five to expose Australia's lower order.

Shoriful then produced a devastating burst, taking three wickets in five balls during the final hour. He had Beau Webster lbw for a golden duck, before Cummins edged behind to Litton Das and Mitchell Starc was bowled with the very next delivery.

Dismissing Starc carried its own significance, given the Australian pacer had ripped through Bangladesh's batting earlier in the day. Shoriful stayed light-hearted about the exchange.

"Starc got me out, and I was trying to do my job with the ball too. It happened, Alhamdulillah," he said.

The day held one more coincidence for Shoriful, who finished with figures to match his childhood idol.

"I've watched him since my age group days. I really like his bowling and swing. Now I'm playing in the same match as him, and we've both taken six wickets. That feels really good," he said.

An unbeaten 51 from Cameron Green helped Australia close on 165 for eight, a lead of 101, with Nathan Lyon unbeaten on 10 alongside him. Shoriful finished with figures of six for 35, his best return in Test cricket.

Batting at number 11, Shoriful had also top scored for Bangladesh with 14 earlier in the day, making him the first cricketer to score his team's highest total at number 11 and take the most wickets for the opposition in the same innings.

At the press conference, Shoriful played down Bangladesh's poor batting. He said, "The game is not over yet. Only the first day has gone. We had a bad day with the bat today. But their batters are also struggling in their own conditions."

"Let's see what happens, and how much we can fight back in the second innings," he added. On the conditions, he said, "You watched the game. The new ball was swinging, for almost 20-25 overs. They took advantage of that."

"We will probably try in the next innings so that our batters can make a good comeback," Shoriful said. "It was a bad day for us. Not just for us, they are also struggling. InshaAllah, we will do well in the next innings."

On his own bowling, Shoriful credited his preparation. "Today was my first five-wicket haul. This is what I did in training. I tried to set myself up when I came into the match," he said.

"The ball is still moving after 30 overs. This is helpful for our fast bowlers," he said, before explaining Mackay's swirling wind. "We were bowling from that end. The wind was against us there, so the ball was swinging a little more."
