Following the success of the first three Australian Narrow Gauge Railway Conventions held in Melbourne (twice!) and Sydney's Blue Mountains, the Brisbane convention was held over three days during Easter 1999.

The venue was the Queensland Railways Institute Conference Centre, located in the central business district directly above Brisbane's Central Station and hence ensuring easy access from most parts of Brisbane. The registration fee for the 4th Australian Narrow Gauge Convention was AU$80.00 per person, and this one-off charge covered the two days’ presentations and clinics, close-up viewing of some of Australia’s finest NG model railways, access to a range of specialist traders, morning and afternoon teas, and one copy of the Convention Handbook which included presenters' notes and diagrams.

A three course dinner was available on the Saturday evening, and attendees entered both models and photographs in a range of competitions. The now traditional convention shirt – this time, a T-shirt with open neck collar and breast pocket - featured the convention's logo and sold well at AU$25 each.

Many of the participants and their families ventured to the north-west on Easter Monday to visit the Australian Narrow Gauge Railway Museum Society’s The Durundur Railway - at Woodford, approximately 75 kilometres north-west of Brisbane.  The society (a.k.a. ANGRAMS) operates two-foot gauge equipment over one kilometre of track, and demonstrated a number of locomotives that are not normally operated on the museums scheduled public running days.
