Since we discussed Mobile Phones and Emergency Numbers we received a few queries as to who exactly is the Emergency Services Telecommunications Authority (ESTA) and what is their function. In Victoria the emergency service dispatch and call-taking for police, metropolitan ambulance, and both rural and metropolitan fire services, is handled by the Emergency Services Telecommunications Authority (ESTA). This means that when you dial 000 (triple zero) these are the guys who organise the appropriate response. But most walkers, cyclists and climbers probably don’t realise that ESTA are also the guys who install and manage those funky green Emergency Markers which dot our bushwalks (such as those in the Lerderderg Gorge), cycle paths (such as those along the Yarra River and Capital City Trails) and some climbing areas (such as those installed at various cliffs in the You Yangs). When an Emergency Marker is quoted, ESTA’s 000 transmitter can then provide specific navigational information to the responding emergency services. So, as you can see, ESTA really does play a vital role within our outdoor community.
I recently chatted to Jeff Adair (Manager Emergency Marker program at ESTA) and he is very keen to promote the roles and benefits of ESTA within our outdoor community. He provided us with a couple of interesting files. We have converted them to PDFs and have included them at the bottom of this post.

Here are a few interesting links:
You can check out ESTA’s web page at: ESTA.
Calling the Emergency Call Service from a mobile phone: FAQs.
Parks Victoria’s Emergency Markers page.
You can also email ESTA at or you can contact Jeff Adair directly on 03 86561218 to discuss any feedback or faults found with any Emergency Markers.

    I notice the pdf file of ESTA emergency marker locations does not show as one page as it is being represented as portrait style when it really should be landscape. Anyone who uses the file in its current orientation may confuse some of the data. Other than that ESTA is very supportive of Open Spaces for their support.

    1. Hi Jeff,

      Thanks for the heads up. The pdf issue has now been rectified and people will be able to view the pdf as it should be in landscape
