Officers from Chifley Local Area Command raided the home on Boyd Street in Kelso following an investigation into drug and property crime.

Police seized nearly 25 grams of crystal meth (Ice), 20 ecstasy tablets, 90 grams of cannabis leaf and about $5,000 in drug money.

Also found was an illegal handgun and ammunition, plus a knife and large bag of illegal fireworks.

Officers were forced to call on the services of a local reptile handler to remove a Diamond Python and a Corn snake from inside the home.

Police arrested a 35-year-old man at the home and he was taken to Bathurst Police Station.

He has been charged with 16 separate offences, including supplying prohibited drugs, the possession of unregistered firearm and possession of explosives without permit.

The man has been refused bail and will appear at Bathurst Local Court on Friday.
