Prosecute desecrater:NT traditional owners

Angry Northern Territory traditional owners are calling for a tradie who defecated on an indigenous sacred site in Central Australia to be prosecuted.

The NT man was sacked after footage emerged of him standing on huge granite boulders known as the Devils Marbles, 100km south of Tennant Creek.

People filming the video can be heard laughing as he removes his pants before defecating on the popular tourist spot.

Individuals who desecrate a sacred site face heavy fines or a maximum penalty of two years in jail.

The tradie was in the region to work on a power station upgrade, and contractor Clarke Energy has issued a public apology to traditional owners over the incident.

Custodians of the Devils Marbles, or Karlu Karlu, are deeply distressed and believe it has demeaned their culture.

"They are feeling very hurt and angry," Central Land Council chair Francis Kelly said.

Mr Kelly said one elder told him the alleged offender was "s******g on our culture" and that "in the old days he would have been speared in the leg".

The CLC has asked the Aboriginal Areas Protection Authority to take legal action under the NT Sacred Sites Act.

Traditional owner Sonny Curtis also demanded an alcohol ban at Karlu Karlu, saying drinking promotes disrespectful and unsafe behaviour.

Traditional owners also want the tradie's former company, subcontractor Nilsen Electrical, to apologise to them both publicly and privately.

In 2013 a mining company was fined $150,000 for damaging a site known as Two Women Sitting Down at Bootu Creek, north of Tennant Creek.
