The Australian Antarctic Division's new Mawson Station leader has reportedly been sacked just days before he was due to leave for the icy continent.

The Antarctic Division's website says former Australian special forces soldier and sculptor Ian Young was to take up the baton as Mawson Station leader this year.

But Mr Young has revealed on Facebook he has been sacked by the Division.

On his profile page, he says he is "gutted he will no longer be going to Antarctica", and he is in shock over what he claims are "unsubstantiated complaints made at the last minute".

He claims he was sacked after two women allegedly complained about excessive drinking and offensive or insensitive remarks.

Mr Young says he will fight what he calls an unfair dismissal.

Antarctic Division spokeswoman Patti Lucas says it was a staffing issue.

She would not say if Mr Young has been replaced, adding that it was an internal matter.
