"We're seeing a lot of guys and talent coming through Australian cricket (and) I think it's important we're leaving those opportunities open there.
"At that stage you will probably get two spots open up in the team with me and Finchy (Aaron Finch). He wants to go to that World Cup in three years' time as well, so there's going to be a few spots available after that."
Warner sets 2023 ODI World Cup in India as ‘ultimate goal’
Warner has accumulated 2207 runs in 79 matches at an average of 31.52 with a strike rate of 140.48, including one century and 17 fifties. His highest individual score in T20 international cricket is unbeaten 100.
However, the southpaw has said he is feeling fitter than ever despite missing two of the last three years of cricket and making it to the 2023 ODI World Cup remains his "ultimate goal".
The Covid-19 pandemic, which has so far infected more than 40 lakh people globally, has brought all cricket activities to a halt and derailed Australia's upcoming international schedule.
"In the last three years I'll have had almost two years off, depending on when we play cricket again," Warner, who lost 12 months due to a ban for ball tampering in 2018, was quoted as cricket.com.au.
"The longevity in your body helps. The get ups of training and playing gets harder as you get older but I haven't felt any fitter in my career than I do now.
"As the legs get older time will tell. At the moment I'm feeling as fit as a fiddle and if I can keep running between wickets as well as I have done, who knows. That (2023 ODI) World Cup is the ultimate goal."
Australian stars in Big Bash League
There were reports that a window might be created for Australia's international stars to play in the Big Bash League.
Warner, who hasn't played a BBL game in last seven years, said he will take a call on whether to return to the domestic league depending on how the summer schedule pans out.
"All my decisions are based around how much playing and touring I'm doing in the summer," said Warner, who last played a Big Bash game between the third and fourth Ashes Tests in the 2013-14 summer.
"It would be easy to sit here now and say 'Yes, I'd like to play' but I have to see what is happening at the end of the year. I'll have to have a hard think about it depending on the schedule."
‘Hard to switch between Tests and T20s’
The 33-year-old said he finds it difficult to switch between Tests and T20s.
"When I last played a game (BBL), my mindset in next two Tests was cluttered between playing and not playing shots," he said.
"I know that's how I play but I've reined it in a lot over the last few years and don't want to be putting myself into a situation again where I'm playing a Test match and then a T20 and then Tests again a few days later.
"I just want to have that one rhythm going into it.
