Police in the Gympie region are appealing for information after a large truck and trailer carrying heavy machinery were allegedly stolen from the Toolara Forest area.

The investigation centres on a white 2000 Western Star 4800 Series prime mover and a Mammoth Float trailer that was carrying a bulldozer. Police allege the combination was taken from a holding yard near Gympie during the evening of September 6.

The incident has prompted an investigation involving Gympie police, with officers seeking information that could help establish the movements of the stolen vehicles and identify those responsible.

According to police information reported today, the bulldozer was later located more than 200 kilometres away in rugged terrain near Gaeta. The discovery of the heavy machinery some distance from where it was allegedly taken has added another element to the investigation.

The truck itself was reportedly last seen in the Gin Gin area. Police are continuing to investigate its movements and are asking anyone who may have seen the distinctive vehicle, trailer or machinery combination to come forward.

A man has been charged in connection with the alleged theft and a wider series of offences. Police allege the investigation involves more than 50 charges, including vehicle theft, fraud, driving-related offences, obstruction and property offences. No pleas have been entered in the matter.

The case highlights the challenges involved in investigating thefts of large machinery, particularly when heavy equipment can be moved between regional areas. The distance between Gympie, the Toolara Forest area and locations where the machinery was later found has made information from members of the public potentially important to investigators.

Police are particularly interested in information about the stolen truck and trailer, including sightings around the time of the alleged theft and during the period when the vehicles travelled through the region.

Residents, motorists and people working in forestry, transport and other industries may have information that could assist investigators, particularly if they noticed unusual movements involving a large prime mover and trailer.

The investigation remains ongoing, and anyone with relevant information is encouraged to contact police.

The alleged theft occurred earlier in September, but the police appeal and court developments were reported on September 14, making the case one of the latest verified crime stories connected with the Gympie area today.
