However, having people and kangaroos in close proximity can lead to problems. Many concerns are centred around the Anglesea Golf Club, but kangaroos can be encountered almost anywhere in town. To address community concerns for the kangaroos of Anglesea and the surrounds, in 2003 the Kangaroo Advisory Group (KAG) formed with representatives from the Department of Sustainability and Environment, Parks Victoria, ANGAIR, Alcoa, University of Melbourne, Jirralingah Sanctuary and other stakeholders. One important aspect for the management of kangaroos in Anglesea has been the collection of accurate data and information on the local kangaroo population. Together with KAG, Dr. Graeme Coulson from the Department of Zoology at the University of Melbourne has set about supervising research programs on the biology and behaviour of kangaroos in Anglesea. The first official census of the Anglesea Golf Club was conducted in 2004 by Honours student Helen Catanchin and it was found that the golf course supports a population of more than 300 kangaroos. In 2007, Teigan Allen tagged kangaroos at the Golf Club and nearby Camp Wilkin as part of her Honours Project. Each kangaroo she caught now has a bright collar with its name on it, and reflective eartags to help identification from a distance. Teigan found that the population density at the Anglesea Golf Club was the highest ever recorded for this species. She also found that Anglesea kangaroos are much more approachable and have much smaller home ranges than their non-urban counterparts. Over 115 kangaroos have now been collared and/or tagged in Anglesea. To assist in the research of recording movements of the Anglesea kangaroos, the researchers encourage people to report any sightings of kangaroos with collars using the KAG incident form. Another initative of KAG was the inaugural Kangaroo Awareness Week held in August last year. The aim of the week was to increase awareness in the broader community of the unique urban kangaroo population we have living in our town. Good news is it’s on again from August 18 - 24, 2008 and local residents can be involved by taking note of where they see any kangaroos during this week (with and without collars and/or tags) and filling out the KAG incident form.

I encourage everyone to do their bit to help the evironment by thinking twice before printing off an email, by using double side printing, recycling printer cartridges, paper etc. We also see you out of the office and doing your environmental bit in the sunshine? I love to get outside and participate in clean up days/tree planting and also being involved in ACTION days. It’s very rewarding. Given this month’s theme of kangaroos, we believe you hit one recently? Any advice for others out there? Yes, I did hit a large kangaroo, (it did survive) it happened quickly with no time to think. No matter what time of the day you should always be aware that one or more can jump out in front of you. Take extra care at dawn and dusk. Travel at a safe speed especially in high risk areas like Coalmine Road. Kangaroos are unpredictable and you never know which way they will jump. ...GRACE McKENZIE
