Maxwell said on Thursday he felt as though batting below Wade at No.6 for Victoria in the domestic Sheffield Shield cricket hurt his selection chances for Australia's third Test against South Africa in Adelaide last week.
Captain Steve Smith and Australia's leadership party fined Maxwell for what they termed his "disrespectful" comments towards his state skipper and ODI teammate Wade.
Head Coach Darren Lehmann said Maxwell's words in a media conference were "disappointing" leading to Smith and Australia's senior members to impose a fine on the 28-year-old.
"I've expressed that to him myself and spoke to the team.

"The wicketkeeper should be batting at seven unless you're trying to squeeze an extra bowler into your line-up."
