Poort, who represented Australia in the 1500 metre freestyle at the 2012 London Olympics and the 10km marathon in Rio De Janeiro in 2016, fronted Wollongong Local Court on Tuesday morning charged with one count each of unlawful entry onto enclosed lands and property damage.

It is alleged the 24-year-old entered a unit complex in Park Street sometime between 4.25am and 4.45am on June 29 and "intentionally or recklessly" damaged the front door of an apartment belonging to a man named William Lampe.

Poort was arrested by police at 4.45am and taken to Wollongong Police Station where he was charged. He was released without bail.

Further details of what occurred that night are yet to be publicly revealed.

Meanwhile, Poort had his case adjourned for six weeks in court on Tuesday so he could get legal advice.

Poort, a protege of famed Illawarra swim coach Ron McKeon, captivated the nation during the Rio Olympics when he employed bold, front-running tactics in the 10-kilometre open water event to lead for the majority of the race.

But his hopes of securing a medal were dashed when he was overtaken in the last kilometre, and he finished in 21st position.

Poort's swimming career took a dramatic turn in 2017, when he was banned for 12 months for failing to be available for drug testing while returning home from an event in Perth.

Travelling overseas after competing at the 2016 Olympics, Poort twice failed to update testers of his whereabouts while in Europe, the third strike in Australia an automatic suspension.
