At least 500 P&C groups across NSW will be sent an information pack with advice for parents on identifying if their child is being "indoctrinated" by "radical gender activists" at school.

The political lobby group Binary will distribute the packs, launched on Wednesday in NSW Parliament by One Nation MLC Mark Latham, around the state from next week.

The packs also have the backing of Finance Minister Damien Tudehope, who had planned to join Mr Latham to launch the kits but was called away on parliamentary business.

Several MPs were also at the launch, including Corrective Services MP Anthony Roberts, Mulgoa MP Tanya Davies and upper house MLC Matthew Mason-Cox.
