CREDITORS of failed property developers Glenn and Lorilea Duker suffered another set-back when Mrs Duker declared herself bankrupt, owing about $11million.

The Dukers, through at least 30 companies, have operated various real-estate schemes in Queensland, Victoria, NSW and possibly Western Australia.

Mr Duker, a former Gold Coast solicitor and preacher, went bankrupt in January, owing more than $40million to 63 creditors. The creditors had hoped to reclaim missing funds through Mrs Duker, but that hope has now been dashed.

The bankruptcy report, released last week, showed Mrs Duker, 34, had sold, transferred or given away six Queensland properties in Camp Hill, Mermaid Beach and Seven Hills in the past five years. Assets listed included a property in Camp Hill worth $650,000 and another in West End worth $875,000.

But accountant Scott Bennison said most of the Dukers properties had at least one mortgage attached and creditors were unlikely to receive money from those assets.

Mr Bennison, who represents a group of Queensland creditors, said the Dukers had set up two-dollar companies and had no intention of repaying the people they did business with.

He said creditors might be able to take legal action against professionals, including their solicitors and accountants, involved in the transactions they had with the Dukers through the professionals' indemnity insurance.

"Glenn Duker often acted as solicitor in transactions between clients and his own companies which is a conflict of interest," he said. "Some of the advice creditors were given was blatantly negligent so they might be able to sue because of this."

The Dukers, whose last known address is in Brighton East in Victoria, could not be contacted for comment.
