Can I fly in and out of Australia with an unpaid fire related fine? [closed]

So a few months ago I was given a $650 fine for "lighting a fire in a national park" and I remember the police officers mentioning something about us breaking a federal law.

Now I disputed the fine as I did not light any fire and was falsely accused and after some time I was asked in an email to provide full contact info of the person who lit the fire in a statutory declaration. Now I don't have any of these details so I tried to contact the Infringement Notice person I was in contact with via phone and email and was ghosted. It is now past the date they gave me and I am about to go on holiday to New Zealand.

Am I going to face any issues at the airport over this?
