As Jono said it's Seafords area, but if the caller said Mclaren vale as the suburb to comcen then Mclaren Vale is going to get the job as Quarry Rd goes through Mclaren vale & Old Noarlunga. If the caller said Old Noarlunga then this thread wouldn't exist. Its not something I'd be losing sleep over pixie.
As with the fluffed pages for our area, it comes down to a notification system which was designed to work well for the caller who knows exactly where they are - traditionally they are in their own home, from their own fixed line.
That data is fed into a turn-out system designed around the metro UBD - short streets in small suburbs. Quote the UBD GR of the street name & your appliance will land within 100M or so of the job.
The real world as we now have it, has travellers who don't know their locality, let alone what road they are on, calling from mobile phones which could be anywhere. This info feeds a turn-out system that doesn't cope well with country distances or multiple possibilities.
We'd do well to turning our collective brain-power towards solving these two core causes, rather than merely whinging that Adelaide Fire got it wrong again. They, we, & the public are victims of a system that hasn't changed with our world.
In my opinion, we should be pressing government into spending cash on position-fixing technology and RAPID replacement, preferably this century. AdFire management needs to revisit scripting & tools so that dispatchers can better interrogate callers who are between towns (landmarks, terrain vs on-line topo maps, just like the CFS OCO's used to do before they were "assimilated").
That just leaves the callers who confidently quote the wrong street name &/or locality... don't know how one fixes that.
That's my two bobs worth, anyway.
