MS Wanganella was an Australian-registered ocean liner built by Harland and Wolff that entered service on the trans-Tasman route in 1933. Originally named Achimota, she was acquired by Huddart Parker after the original sale to Elder Dempster Lines fell through.

Huddart Parker Ltd was an Australian shipping company trading in various forms between 1876 and 1961. It was one of the seven major coastal shippers in Australia at a time when shipping was the principal means of interstate and trans-Tasman transport. The company started in Geelong, but in 1890 shifted its offices to Melbourne. By 1910 Huddart Parker had grown to rank 24th of the top 100 companies in Australia by asset value. Several of the company's ships served in World War I and World War II. Huddart Parker ceased to be an independent company in 1961, when it was taken over by Bitumen and Oil Refineries Australia Limited.
