Helo is pretty bloody inefficient when you aren't doing broad scale wipeout type ops though at a heavy bait sowing rate (which is no longer an option on a lot of land due to the new rules). Also a lot of animals could be getting sub-lethal doses and a good training session to pass onto the next generation of animals from what I hear. Last time I was in an area after a dosing the weathered baits were still visible but seemed to have collected at the low places where water flows. Not ideal for success rates.
Going forwards the word is we will need to look at options shortly as the use of the traditional aerial method with some of the success rates being reported as not flash. Whether the operation is a success or not still relies on getting people in to place traps among other info gathering tools, which is a bit of an irony for my thinking. A lot of the areas where it's deemed as too rough to put people into are also not entirely suitable for aerial for the same reason as above, baits wash down really quickly.
Shame of it is by doing so much aerial, as noted ground based people on top of their game are a very rare breed as there just hasn't been the work for them. A lot of questions and not many answers!
