A WA land owner has gone to great heights to honour the Holy Spirit with a three-year crusade to build a 10-metre crucifix near the Kwinana Freeway.

Nick Smargiassi, who owns a property along Stock Road in Stake Hill, north-east of Mandurah, had his first application to erect the massive white cross rejected by the shire in 2012.

He has been fighting to have the decision changed ever since.

"I just want to say 'God bless you on the freeway', what is wrong with this?" he said.
