Australian Central Credit Union increased revenue for the 2008 financial year by14 per cent to $240 million, but tighter margins caused net profit for the year to remain flat at $12 million.The credit union is looking for alternative revenue streams, building on its experiments to operate more as a mortgage manager and broker when customers are looking for a home loan.Managing director Peter Evers yesterday said they are looking to purchase more residential portfolios, after last month closing the acquisition of the $310 million Mortgage Find portfolio from Royal Automobile Club of WA."Now that we have moved into this space, we see the opportunity to grow substantially through the acquisition of portfolios."Evers adds a portfolio purchase bigger than the RACWA deal is possible in the short term."Certainly it could be bigger. We have some attributes around the size of the portfolio we are looking at, and we would be keen to acquire additional portfolios in the next twelve months."ACCU has recently entered the broker market, offering loans from a panel of twelve other lenders. Evers said the increased product range will help the West Australian expansion."We are planning to grow into Western Australian quite strongly over the next two years. We have a good wealth management business there and we have been looking to complement that with retail home loans, hence the RACWA acquisition."Then we can move into the West Australian market with that service (broker), rather than just our own product, as we are not a known brand there."Evers added the credit union will look to re-enter the securitisation market in the next six to twelve months, if it becomes more active.Deposits increased five per cent to $1.5 billion during financial year 2008, with total loans under management just over $3 billion - which includes loan portfolios under advice.
