The liquidator of the collapsed Mowbray College is still pursuing dozens of families who have failed to repay remaining fees.

Liquidator Jim Downey said about 45 families, who owed about $300,000 between them, had not repaid their debts after the western suburbs college collapsed in 2012.

Mr Downey has also launched bankruptcy proceedings against a small group of parents.

''We consider that very much a last-ditch effort after all other means of resolving the situation have been exhausted,'' he said.

Some parents are still paying off the remaining fees through repayment plans.

''Some are paying directly via their employer on a monthly basis. But where we've been met with silence or no reasonable offer is forthcoming we're left with no alternative than to issue bankruptcy proceedings.''

The greatest remaining debt from an individual family was about $25,000.

Mr Downey is attempting to reclaim up to $1 million in total. He said he had clawed back several hundred thousand dollars so far.

An investigation in the Supreme Court last year revealed the school had accumulated about $28 million in debt when it collapsed.

A former board chairman told the court in June that the college's financial woes grew worse when parents became increasingly worried and began withholding fees.

Meanwhile, plans to open a new primary school at a former Mowbray campus in Caroline Springs have hit a snag and it will not be ready to accept students this year as planned.

Wyndham councillor Intaj Khan bought the site for more than $6million. But he said he could not complete a submission to the Victorian Registration and Qualifications Authority to open the new school because of ''time constraints''.

He now plans to open the school by 2016.

''I have not given up and this is something I would like to do for the community,'' he said.

However, Mr Khan said the school's board was now undecided about whether it would open as a primary or secondary school.

Mr Khan said he had already received 80 applications for his proposed school. But he insisted more would flow once the school was accepting enrolments.

Mr Khan estimated the new school would need a minimum of about 220 enrolments to be viable.

The school was to be called West Melbourne Grammar but Mr Khan has since decided on the new name West Lakes Grammar School.

The school would charge ''reasonable fees'', but Mr Khan did not provide a figure. He said he had found a high-profile principal but would not reveal a name.

Mr Khan said he had barred other schools and organisations from using the campus. ''I do not want to touch it or have someone else damage the property.''
