The couple accused of trashing a Gold Coast mansion rented for them by Clive Palmer after the death of their son have said that they did not trash the $1000-a-week property - it is all simply a miscommunication.

Jaryd Campbell and Belinda Warwick lost their son Roman in a house fire in May.

Residents of Beenleigh, south of Brisbane, were keen to help the family - with the Logan House Fire Support Network raising more than $100,000.

Jaryd Campbell and Belinda Warwick have been accused of causing up to $40,000 in a Gold Coast waterfront property rented for them by Clive Palmer at a cost of $1,000 a week

Seeing the vision of Mr Campbell rushing towards the burning house in an attempt to rescue their son, Clive Palmer wanted to help as well.

Having rented the family a $1000-a-week waterfront mansion on the Gold Coast - he could now be left to pay up to $40,000 for the repair bill.

"He's given them this beautiful property for six months rent-free, this car, another car and this is the end result," Logan House Fire Support Network founder Louie Naumovski told A Current Affair .

"This was their opportunity to make a life for themselves after the tragic event, but I don't know how someone could live like this and do this in six months time," he said.

But Mr Campbell and Mrs Warwick said the damage was not intentional and that they planned on having it repaired.

"It's just such a massive thing to lose a child, like we got so much help but it wasn't our stuff, you know. It was not our stuff. Nothing was familiar and we just tried so hard," Mr Campbell said.

"It was supposed to get cleaned up we would never just never walk out on a place," he said.

Mr Campbell claims that the couple had organised for a plasterer to attend to the property to patch-up two "small holes" he had punched in a wall following his son's funeral.

He also said that they had organised a cleaner to come to the property after they moved out, but they never arrived.

But Mr Namovski says that the damages go beyond simple wear-and-tear and include doors off their hinges, ruined carpets and three cats, which were abandoned at the property.

The couple say that it is unfair the property's damage was made public, as they are still grieving.

"It's not very fair actually. We have gone through enough and now to have this on our shoulders as well, we just feel like the lowest people in the world at the moment," Mrs Warwick said.
