So if mapping stops at 12.05 then this puts Theo close to the beach waterline at 12.05, after he leaves the prickly area. Theo is on his phone from 12.23 am, 18 minutes after he switches off tracking. Did Theo turn off mapping to save power then decide to watch youtube if worried about battery? Or did Theo turn off mapping worried about being tracked by someone who knew his phone number? First flight, then think of this possibility so to make sure he switches off Google Maps. All someone needs is his phone number and can find his location through "find my phone" or there are other easy methods. Taking into consideration it does appear he was trying to escape someone this is a real possibility. If so then this means whoever was after him had his number. Also between 12.05 when he must have changed settings on his phone to 12.23 am when he began using his phone there is a period of 18 minutes in between. If not on his phone, then what was he doing in those 18 minutes in between? This points to somebody else being with him, as do other clues, such as the choice of Milne Track, bush routes etc. In those 18 minutes in between IMO he was engaging with someone, talking. If alone he would have likely used phone sooner, and also be more likely to be trying to get home rather than sitting there on a dark night with no moon. If Theo was going to try climb the cliff to get to the lighthouse why didn't he do it when he thought he was in danger? He was hiding rather than try climb cliff which would have been quite impossible at night anyway. I don't think Theo went into a prickly area for the toilet, pitch black night why even need privacy? Why go into a difficult area? IF for privacy then there must have been others present but still he would not need to go into such an area for privacy anyway. I doubt anyone could see more than a few feet ahead. It all points to Theo escaping someone, and more than likely he had company who was escaping with him, and more than likely company he met at Tennyson St. where he was for 7 and a half minutes. It does not seem logical to be almost running to go to a doof party through thick scrub in pitch black. I believe something happened at Tennyson St., and he was either with someone who was in a hurry to get away or Theo needed to get away. Turning off his Google Maps may have been for a different reason than to save battery, it is very possible whoever he was escaping had his phone number and with that the potential of easily finding his location.
