Australian opener David Warner has revealed he has likely entered the "last 12 months" of his Test cricket career as further World Cup action nears.

Warner, who turned 36 at the end of last month, is set to remain a key piece in Australia's upcoming summer series against the West Indies and South Africa on home soil before Andrew McDonald's men begin planning for their trip to India and another Ashes series abroad.

Still a required player for the red-ball format, it's likely Warner will remain at the top of the batting order for both of those trips, however they could be his last in the baggy green.

With a World Cup taking place in India at the back-end of next year, coupled with a T20 World Cup the year after, Warner has flagged his attention is likely to turn toward the white ball formats.

Speaking to Triple M's Deadset Legends on his future, Warner was candid on his likely career roadmap.

"Test cricket will probably be the first one to fall off," the veteran batsman said.

"Because that's how it will pan out. The T20 World Cup is in 2024, (one-day) World Cup next year.

"Potentially it could be my last 12 months in Test cricket."

Despite a disastrous T20 World Cup campaign on home soil, where Warner amassed just 44 runs from four innings, Australia's big-hitting opener remains confident in his short-format ability.

With the next T20 World Cup already 18 months away when the tournament kicks off in the Caribbean and USA, Warner expressed his confidence in being among Australia's squad for another tilt at the title.

"T20 cricket - I love the game. I will be looking to get to 2024," he said.

"For all those people saying I am past it and a lot of those old people are past it, look out. Be careful what you wish for."

Warner is nearing the 100-match milestone for both the Test and T20 formats at the international level, having played 96 and 99 matches respectively.
