Here are couple more Australian technology stocks to add to those listed by crystalblue on 2nd May. They are in the $150M to $250M market cap range, and have world leading technologies, proven success in worldwide sales, revenues of $45M to $90M (FY19E) and revenue growth rates of 20% - 38%.

Atamos (AMS) P/S = $144 M / $45 M = 3.2
Catapult (CAT) P/S = $250 M / $90 M = 2.7

My take on all this is that you can pay P/S of 12 to 45 for the larger ($3 B to $7 B), well-known Australian companies with world-leading technogies and wide markets, or 2.7 to 3.2 for the smaller (around $200M), lesser known Australian companies with world-leading technogies and wide markets.
