A top One Nation adviser has faced a Brisbane court after being charged with assault offences.
Media adviser to Queensland-based senator Malcolm Roberts, Sean Black, appeared in Brisbane Magistrates Court on Wednesday afternoon, after being taken into the Police Watch House earlier in the day.
The 39-year-old has been charged with three counts of common assault, as well as three counts of assault occasioning bodily harm.
The court heard the alleged offences were historical, with some dating back as far as 2007.
He was granted conditional bail, which was unopposed by police.
Magistrate Jacqueline Payne found he did not pose a flight risk, after the court heard Black had plans to travel to England with his wife in September.
The former Logan City councillor and real estate agent appeared calm in the dock after being led into court.
He also previously worked on former Liberal National Party MP Michael Pucci's 2012 election campaign and was associated with the Labor Party in the 1990s.
He was once married to LNP candidate and former Beaudesert Shire councillor Hajnal Ban.
In February, Mr Roberts wrote on Facebook that his staffer was "a great asset", "hard working" and "a personal friend".
Black refused to speak outside court while One Nation party leader Pauline Hanson's chief-of-staff James Ashby also declined to comment.
The matter will return to court on June 19.
