I can remember someone on this thread (apologies to whomever it was) saying that they'd pinged the FTP tower when they were driving within the Brookfield area. I google-mapped it at the time and thought - ooh that's interesting; GBC would have driven down there every day.
Think we need to let go the line-of-sight idea with the towers and expand our vision more peripherally.
Unfortunately, though, MM, line-of-sight is how they work. Occasionally one can get a reflected connection, but in general terms, it IS line of sight. And as has been discussed before, the only area in Brookfield where I would think line of sight to the FTP tower may be possible would be down around the Rafting Ground Reserve, on the river side of Moggill Road, where the FTP tower is just about in the line of sight.
The problem with Brookfield is that it is hilly. And in the centre of Brookfield - all around the BC house, for example, they are in line of sight to much closer towers, specifically the Brookfield tower which is just across Moggill Creek on Upper Brookfield Rd, or the Kenmore tower which is on Moggill Rd up in the shopping centre of Kenmore where Moggill Rd takes the turn opposite the church to run back down the hill towards Skull Manor. That tower would be in line of Brookfield, and it would also be BETWEEN Brookfield and the FTP tower, which is another hill further away.
That line of sight principle is why I get a signal in some parts of the house and not others. And why people need to go out onto the verandah and search for the magic spot to get a connection in many places. I'm sure many here would be familiar with that phenomenon.
I'm actually down in the Tasmanian Highlands at the moment, and have a Telstra 3G connection on one side of the house but not the other. The tower is about 4 Km away. As I walk or drive around the area here, I can get signal from 5 bars to zero over a space of a few metres.
So - I think your idea has great merit - and can only be explained by the phone having been moved from where it may have been pinged by the app originally (eg by an enterprising police officer using GBC's phone) and where it ended up in range of the FTP tower. As you pointed out, this almost certainly could only have happened in that time between the first police response, and the execution of the search warrant in the afternoon.
And while GBC would have been watched closely, the same degree of monitoring may not have been applied to others....
