Already Test cricket's leading wicket-taker with 685 scalps, Warne said he hoped the series against England would take him past the 700 mark.
"I only need 15, so I'd like to think at some stage during the series I'd get that," he told reporters on Wednesday.
The 37-year-old said there was no need to consider retirement if he was still taking wickets.
"I'm probably fitter now than when I started, also I think it's dictated by performances - if you're performing your role in the team well, it really doesn't matter about your age," he said.
"As long as we're playing good cricket and we're winning and we're fit, I don't think that'll come into it at all."
Warne was non-committal when asked whether the Ashes series beginning Nov 23 would be his last.
"If it's my last series it's my last series," he said
"I don't know whether it will be or not, retirement is about enjoyment, it's very enjoyable playing cricket for Australia at the moment.
"We've won 11 out of 12 Tests since the Ashes, we've played well, I enjoy playing under Ricky and we've got a good group of guys together.
"How long that lasts, whether it's two years, three years, four years -- who knows? I'm only 37."
