Victorian based accounting and consultancy firm Nexia Melbourne is to join the global practice Moore Stephens as its state representative in the coming months.

Confirming the board's decision today, Nexia Melbourne Chief Executive Officer Steve Sakkas said the firm would be aligned with a strong Moore Stephens brand globally and benefit from its complementary strategic plan to generate growth in Australia and the broader Asia Pacific and China regions.

"The strength of the Moore Stephens brand will enable our firm's staff, directors and clients to have access to a broader group of professionals internationally," Mr Sakkas said.

"Moore Stephens has always had a strong reputation and proud history (since 1907) in 'private client' services, which is an area closely aligned with ours. It will provide our clients with a quality Australian firm with enormous depth that is focused on 'private clients'.

"While we have signed the membership agreement, the timing of becoming Moore Stephens' Melbourne representative is yet to be finalised."

Moore Stephens has 292 firms operating in 626 offices within 103 countries and with annual fees income of almost $US2.7 billion.

Mr Sakkas said it is "business as usual for the Nexia Melbourne office" with no changes to the firm's servicing of its clients or management of its staff.

Nexia Melbourne has 16 directors, 100 staff and annual revenue of $20 million.

Moore Stephens Australia Chairman Don Boyd is excited by the firm's recent expansion.

"Following closely on the announcement of our merger with UHY Haines Norton in Perth, this is a real vote of confidence in the strength of the Moore Stephens brand and in our strategy of always behaving as one firm and now in conjunction with a significant and high-performing Melbourne firm," Mr Boyd said.
