Morrison said on Thursday (January 13) he did not want to comment on Novak Djokovic's visa status and that it was up to the immigration minister to decide whether to revoke it or not.
He later added the government's policy on visa holders "hasn't changed".
Djokovic was confirmed in the official draw for the Australian Open men's tournament despite uncertainty over whether the government will cancel his visa for a second time.
Immigration Minister Alex Hawke is weighing exercising his discretionary powers to revoke top seed Djokovic's visa, which could scuttle the Serbian superstar's bid for a record 21st major tennis title at the Australian Open.
