HSBC Centre.  105metres.  25 storeys.   Completed 1983.

Up to 1998, this building was Colonial Mutual headquarters until the HSBC moved in.  Having once been Colonial Mutual, their old headquarters was across the road.
 

 
Now the Manor Apartments (right), this was once Brisbane's tallest building at 40metres (50metres with Plant Room) behind the City Hall at 85metres.   Formerly the Colonial Mutual Life building, it was designed by Hennessy and Hennessy and was the city's most imposing example of thirties high-rise office construction.
