Symonds has run into trouble with team management in the past
Andrew Symonds has been sent home from Australia's one-day squad playing Bangladesh in Darwin after missing a compulsory team meeting to go fishing.
Stand-in skipper Michael Clarke said it added to a number of other recent incidents which raised doubts about the 33-year-old all-rounder's commitment.
But Clarke said he hoped Symonds would reflect on his punishment and return for the forthcoming tour of India.
He said: "Andrew is disappointed but we need to keep high standards."
Symonds' expulsion for the remainder of the series was made on the recommendation of the Australian team's leadership group.
And Clarke stressed Symonds could only return to the fold if he was willing to conform to team rules.
Clarke added: "Andrew accepts our decision. I know him pretty well and I hope he goes away from this and gets himself right and gets himself back into our team, because he's a very important player and we certainly want him as part of our squad.
"It's so hard to play for this team. In my opinion we are the greatest sporting team in the world, so we have standards and they might be higher than other teams.
"If you don't fulfil those standards, unfortunately you're not going to be a part of our squad.
"I hope he doesn't take it personally because Andrew is one of my closest mates so it's certainly not personal.
"I guess that's why we've made this decision, because we want Andrew back in our team for as long as he wants to be a part.
"But right now, for the best interests of the team, and for the best interests of my friend Andrew Symonds, I believe we've made the right decision."
Australia coach Tim Nielsen admitted he was disappointed Symonds has not been as committed as he could be with the likes of injured Ricky Ponting and absent Brett Lee and Matthew Hayden all unavailable for the match against Bangladesh.
"I believe when we've got such young impressionable faces in our team, we need to make sure our senior blokes are 100 per cent spot on to the way they go about presenting themselves and that was an issue that wasn't being carried out with Andrew," Nielsen said.
Symonds has previously courted controversy over his behaviour.
He was left out of a one-day match against Bangladesh in 2005 after arriving for the game under the influence of alcohol.
Despite Symonds's absence, Australia won the opening game of the three-match series by 180 runs.
The remaining matches will take place on 3 and 6 September.
