A new Commonwealth Development Bank was established in 1960 and during the 1970s the bank diversified its business into areas like insurance and travel. It established a finance company, CBFC in 1974. The bank also became more heavily involved in foreign currency trading and international banking in general.

The bank actively supported the introduction of [[decimal currency]] in the years leading up to 1966 and, like most banks, it gradually converted its paper records onto a new computer-based system. The bank created the first [[credit card]] in Australia in 1974 when it established [[Bankcard]]. In later years the bank began offering [[MasterCard]] (1984) and [[Visa (credit card)|Visa]] (1993) cards as well.

In 1974, as [[Papua New Guinea]] approached independence, the bank formally handed over its PNG operations to the newly created and government-owned [[Bank South Pacific|Papua New Guinea Banking Corporation]] (PNGBC).  The bank retained a restricted branch in Port Moresby that it finally closed in 1982.

In 1981 the bank transferred its operations in the [[Solomon Islands]] to the [[National Bank of Solomon Islands]], which operated as a joint venture (51% Commonwealth Bank, 49% Government of the Solomon Islands).

In 1989 the bank acquired 75 per cent of [[ASB Bank]] in [[New Zealand]].

In 1991 the bank acquired the failing Victorian Government-owned [[State Bank of Victoria]] (est. 1842).<ref>{{Cite web|last=Dixon|first=Robyn|author-link=Robyn Dixon (journalist)|date=2019-08-23|title=From the Archives, 1990: Victoria sells debt-laden State Bank|url=https://www.theage.com.au/national/victoria/from-the-archives-1990-victoria-sells-debt-laden-state-bank-20190819-p52iml.html|access-date=2021-08-11|website=[[The Age]]|language=en}}</ref>
