  • South Australia's National Parks Guide
    SOUTH AUSTRALIA’S NATIONAL PARKS GUIDE Explore some of South Australia’s most inspirational places INTRODUCTION Generations of South Australians and visitors to our State cherish memories of our national parks. From camping with family and friends in the iconic Flinders Ranges, picnicking at popular Adelaide parks such as Belair National Park or fishing and swimming along our long and winding coast, there are countless opportunities to connect with nature and discover landscapes of both natural and cultural significance. South Australia’s parks make an important contribution to the economic development of the State through nature- based tourism, recreation and biodiversity. They also contribute to the healthy lifestyles we as a community enjoy and they are cornerstones of our efforts to conserve South Australia’s native plants and animals. In recognition of the importance of our parks, the Department of Environment, Water and Natural Resources is enhancing experiences for visitors, such as improving park infrastructure and providing opportunities for volunteers to contribute to conservation efforts. It is important that we all continue to celebrate South Australia’s parks and recognise the contribution that people make to conservation. Helping achieve that vision is the fun part – all you need to do is visit a park and take advantage of all it has to offer.

We started our first dive of our trip at Sea Fan Coral Garden. During this dive we found 2 cuttle fish, commensal shrimp, tiny crinoid crab and schooling of neon fusiliers. From place to place we saw nice big gorgonian sea fans. During the second part of the dive we stayed at shallow reef and spotted swimming moray eel. Visibility was reaching 15 m. and there was a mild current. Our chef prepared lunch lunch and moved to south of Gili Trawangan where we dove at Trawangan Slope. This time swell raised and we jumped away on 15 m. depth. At the very beginning we spotted a turtle and red mantis shrimp. At the second part of the dive we saw puffer fish, sweet lips fish and many bat fish.

  • De Eerste Dagen Met Eric in Seghe Honiara, 15 Mei
    De eerste dagen met Eric in Seghe Honiara, 15 mei Een week na het vertrek van James en Sachiko in Seghe komt Eric aan boord. Het gat in de romp is gedicht en op de dag van zijn aankomst kan ik de laatste laag primer aanbrengen. Het plan de campagne is om in vijf weken naar Honiara te zeilen maar duiken en fotograferen komt op de eerste plaats! Eric heeft een prachtige nieuwe Sony Alpha 7R2 camera in bruikleen gekregen en die moet aan de tand worden gevoeld. Geen betere plek dan dat aan boord van de 'ALK' te doen waar Eric en ik, ondanks de ruimtebeperkingen van een zeilboot, ondertussen wel weten hoe en waar we op mooie plekken kunnen komen. Het P38 vliegtuig uit WWII dat in Seghe aan het eind van de landingsbaan is gezonken in 8m diep water, is een mooi begin. Drie mijl ten oosten van Seghe, aan de zuidkant van New Georgia Island, ligt een wir war aan eilandjes waar we een speciale duik maken. We maken kennis met Aldio die hier op zijn eigen kleine eilandje woont. Een kunstenaar die zijn kunstwerken op papier drukt dat hij zelf maakt. Mooi om zijn werk te zien en Jimmy kan de verleiding niet weerstaan om een mooie print te kopen. Aldio vaart ons in zijn bootje door uitgestrekte mangroven en zoutwatermeren tot we in een kloof aankomen. Hier beginnen we aan onze duik. Onder een grote boom zakken we af naar 20m en zwemmen dan op ons gemak door een kloof naar de buitenkant van het rif.

  • The Environmental, Social and Human Health Importance of the Aquifers and Wetlands of the Lower South East of South Australia An
    The environmental, social and human health importance of the aquifers and wetlands of the Lower South East of South Australia and SW Victoria and the increasing threats to their existence. My submission to the Senate Select Committee on Unconventional Gas Mining March 2016 I am Marcia Lorenz B.A. Grad. Dip. Ed. Admin., a retired school teacher. I only discovered the attractions of the South East when I came to Beachport 12 years ago. I am a volunteer at the Millicent High School where I support the Aboriginal children in their work with their culture and the environment. I am also a volunteer with other environmental groups in the region. My submission concerns the likely detrimental effect of unconventional gas extraction (“fracking”) on the aquifers and wetlands of the South East of South Australia and therefore on the myriad of species, both flora and fauna that constitute wetland habitats. 1 HISTORY Historically, post white settlement, wetlands were viewed as wastelands with no thought being given to the natural environment and the diversity of species they contained. Economics was the driving force. It would be wonderful if we could say that times have changed and politically there is the realisation that in order for humans to exist, the natural environment must be taken into consideration. After all we now have knowledge that wasn’t available to the ordinary person in the early days of settlement. Post European settlement change in land use has significantly altered the landscape of the South East resulting in the loss of many areas of wetland habitat with <6% of the original wetland extent now remaining.1 An estimated 2,515 km.

Rizalthus, new genus, with just one species, R. anconis, new species, can be distinguished from allied genera by characters of the carapace, epistome, chelipeds, male abdomen and male fi rst gonopod. Visayax, new genus, contains two new species, V. osteodictyon and V. estampadori, and can be distinguished from similar genera using a combination of features of the carapace, epistome, thoracic sternum, male abdomen, pereiopods and male fi rst gonopod. A new species of Hepatoporus Serène, H. pumex, is also described. It is distinguished from congeners by the unique morphology of its front, carapace sculpturing, form of the subhepatic cavity and structure of the male fi rst gonopod.

  • Thursday 19Th February 1942 by Dennis J Weatherall JP TM AFAITT(L) LSM – Volunteer Researcher
    OCCASIONAL PAPER 74 Call the Hands Issue No. 39 March 2020 World War 2 Arrived on the Australian Mainland: Thursday 19th February 1942 By Dennis J Weatherall JP TM AFAITT(L) LSM – Volunteer Researcher Dennis Weatherall attended the recent 78th Anniversary of the Bombing of Darwin, also known as the “Battle of Darwin”, by Japanese Imperial Forces on Thursday 19th February 1942. The air raid siren sounded at exactly 09:58 - war had arrived in Australia. He asks why more Australians don’t know about the continuous attacks that started on that day and continued until 12th November 1943 - some 21 months. In this paper Dennis provides and overview of the attacks and naval losses in more detail. Darwin, has changed much since my last visit some 38 years ago and it is dramatically different to the Darwin of 1942 which bore the brunt of the first ever attack by a foreign power on Australian soil. Why didn’t we know they were coming? Was our intelligence so bad or were we too complacent in 1942? The Government of the day had anticipated the Japanese would push south but “when” was the big question. Evacuations of civilians had already started by February 1942. On the morning of the fateful day there were many ships, both Naval and Merchant men, in the Port of Darwin along with a QANTAS flying boat “Camilla” and three Consolidated PBY Catalina flying boats of the USN, when 188 Japanese aircraft of various types, 36 Zero fighters, 71 dive bombers and 81 medium attack bombers commenced their first raid.
