The Venturer Unit was registered, as 1st Berowra Senior Scout Troop, on 29th August 1968 (although it had been in existence since February of that year) with Frank Waitzer of Wyanna Street, Berowra as Venturer Leader. There were 7 Senior Scouts (Venturers) in the first Unit. At the time of registration the Group consisted 30 Cubs, 32 Scouts, 1 Cub Scout Leader and 4 Scout Leaders. The Venturer Unit, at the time of registration, came under Muogamarra District and Bill Kirk was Group Scout Master with T Schuit as Group Secretary. The Senior Troop met between 8.00pm and 10.00pm on Fridays. Bill Hamilton was the Venturer Leader between 1978 and 1983. In February 1983 six females, the first females in the Venturer Unit, were admitted. Activities at this time, as recalled by Bill Stevenson, were sailing, caving and abseiling.

The following Venturers (Dianna Bissett, Warwick Bissett, Duncan Armour, Heather-Ann Cairns, Sean Farrell, Michael Farrell, Phillip Harrison, John Harrison, Andrew Introna, Colin Johnston, Andrew Knight and Kate Waddingham) went to Tasmania from 26th December 1986 to 19th January 1987 and walked the South Coast Track and the Overland Track. The money for this was raised with a bush dance, car washes, odd jobs etc.
