I'd really like to thank everyone for their help here. I didn't see any of the recent replies, and coincidentally walked into an art glass store at Federation Square in Melbourne, and lo and behold, there was some Tony Hanning glass there for sale, and those items were in a very similar style, with reeds but other figures (not dragonflies), and they were larger, about 21cms in height I think, and about $1800, so I would tend to agree with Trevor's guess as to value. Tony Hanning for sure. Thanks everyone!
