The aftermath of Cyclone Trevor is sparking fears for Far North Queensland cattle that have been trapped due to rising floodwaters.

Although the cyclone hit the region early last week, rain continued to pound the area well into the weekend, preventing farmers from moving the herds and assessing the damage.

Cook Shire Mayor Peter Scott said many roads are still cut-off by floodwater and urges residents to stay safe and keep out of the floodwater.
