Announced in October last year, the acquisition had been subjected to due diligence and was this week confirmed and completed.

Keddies forecast full year revenue of about $25 million, and Slater & Gordon said it would be a major boost to the firm’s goal to increase its share of the New South Wales personal injuries litigation market.

"We've said from when we listed that leading the consolidation of the Australian personal injuries market was a prime aim for us, with Queensland and New South Wales the main targets,” Slater & Gordon managing director Andrew Grech said.

"Our recent acquisition of Trilby Misso has gone a long way towards our market share goals in Queensland and now the Keddies acquisition will give us a huge lift in New South Wales, in particular in greater western Sydney."

Keddies has offices in Redfern, Ashfield and Liverpool in Sydney, as well as in Wollongong and Brisbane.

The acquisition was to be completed through $3.7 million in shares, the take-up of Keddies' $11 million in debt, plus cash.

The Keddies business will be fully integrated into Slater & Gordon. The Brisbane and Wollongong offices will relocate to the existing Slater & Gordon offices in those locations.

The Keddies Redfern, Ashfield, and Liverpool offices will be rebranded and together with Slater & Gordon's existing Parramatta office, become hubs for Slater & Gordon's personal injuries practice in western Sydney.

Slater & Gordon offices closed

The union is confirmed as Slater & Gordon was forced to close its Brisbane and Ipswich offices this week due to flood and severe weather risks.

The firm made an initial donation of $10,000 to the Premier’s Disaster Relief Appeal.

“The news from Queensland has shocked us all and we will continue to monitor the situation closely. It’s important that our staff and clients in these areas know that we are thinking of them at this time,” Grech said.

“Our firm knows that when the going gets tough, the tough get going and we will be there to support our staff and clients in the recovery.”

Grech said the company would be providing financial assistance if it was required by staff members directly affected by the floods.
