Mitchell Johnson says he regularly thinks about retiring from cricket as he prepares for Australia's second Test against New Zealand in Perth.
Johnson's latest public reference to potentially calling it quits comes just a month after revealing he had considered walking away from the game following Australia's Ashes defeat in England earlier this year.
The 34-year-old showed no signs of letting up as Australia claimed a 208-run win in the opening Test against New Zealand last week, recording figures of 3-105 and 1-58 in Brisbane.
But speaking ahead of the second Test at the WACA Ground, which starts on Friday, Johnson said the thought of retiring is always on his mind.
"I think about it most days. It's probably getting to that time, but to be honest I'm just trying to go out there and play each game and enjoy it," Johnson told reporters on Wednesday.
"It could be after this game I might just go, 'I'm done', but I'm still enjoying my cricket and enjoying the challenges.
"It's a really good time for Australian cricket with these young guys in the team and I want to be a part of that.
"As long as I'm performing pretty well and doing my job in the team then mentally I'm feeling pretty good.
"I started my career in Australia; I played my first Test at the Gabba. I think I'd like to finish my career in Australia if I have the choice. It's just whether I get that choice or not -- not many people do."
Meanwhile, Johnson's team-mate Adam Voges, 36, is ready to make the most of home advantage at the WACA.
Perth-born Voges, the captain of Western Australia at domestic level, is intimately familiar with the venue as he looks to build on his unbeaten 83 in the first innings of Australia's win last week.
"I've had some really good success here over the last couple of years, so I'll take a great deal of confidence out of not only last week, but coming home and batting on my home strip," said Voges, who has scored 12 hundreds and 11 half-centuries in 53 first-class matches in Perth.
"I felt really good in Brisbane. I thought I batted well. I came in at a good time at 3-400 and got to capitalise on the good work our top order did.
"Having said that, I felt really really really good. Hopefully I can continue that into this game."
