Australian musician Luke O'shea has been arrested at a coal mine protest just days after winning a slew of awards at the nation's top country music prizegiving.

O'Shea was the big winner at the Country Music Association of Australia (Cmaa) awards on Saturday night (24Jan15), taking home three Golden Guitar trophies including the prize for Male Artist of the Year.

After the ceremony in Tamworth, he travelled to a coal mine near the town of Narrabri and joined a demonstration against plans to expand the facility and draw water from a local river.

O'Shea is believed to have attended the protest with his father Rick, 71, and chained himself to a water pump at the Whitehaven Coal Maules Creek Mine. He was arrested on Tuesday (27Jan15), along with his dad, and they are both facing charges of entering enclosed land and remaining on enclosed land, while the singer faces an additional charge of hiding tools, according to Abc.net.au.

They have both been released on bail and are due to appear at Narrabri Local Court on 24 February (15).

O'Shea says of the protest, "Farmers in this area are screaming out, they need to be heard and they are needing to be supported and that's what my father and I are doing. I'm not anti-mining whatsoever.. (But) it's just idiocy that this should be allowed to go ahead."
