Expert System - Australian Flags by McGoo Software

Based on the responses you have made:

The flag is probably the flag of the Australian Capital Territory

Conclusion Notes:

The Australian Capital Territory was founded as a Federal Territory on 1 January 1911, and attained self-government on 4 March 1989, however until recently it did not have a flag of its own. The flag above replaces one of similar design, with a ochre-red background that had been been used as the City flag of Canberra. The flag for the Australian Capital Territory was adopted by the ACT Legislative Assembly on 25 March 1993. Competitions were held in 1988 and 1992 in which artists and other interested ACT residents provided a large range of designs for a proposed ACT flag. Some common features from these entries were incorporated into four design options and these were presented by the ACT Legislative Assembly to the ACT community for its consideration in February and March of 1993. The flag above, designed by Ivo Ostyn, was endorsed as the most popular design. The flag uses Canberra's city colours of blue and gold. In the centre of the gold fly is a modified form of the arms of the City of Canberra, whilst the Southern Cross appears in the blue bar at the hoist.

Expert System Rule:

IF on the flag the Southern Cross is visible
AND on the flag there is no Union Jack present
AND the field of the flag is blue and yellow
THEN the flag is probably the flag of the Australian Capital Territory.
