Significance Fourteen days beforehand, Ardern said no new offshore oil and gas exploration permits would be awarded -- evidence she said of the “government of transformation” she promises. The offshore ban does not affect the wide areas already open for exploration and exploitation over the next three decades, but it reinforces the government’s intention to be more active on climate change and environmental protection. Like the government's “wellbeing economics”, this might prove transformative if Ardern can retain office through to at least the next election in 2020. Impacts The offshore oil and gas exploration ban could see earlier withdrawal by major oil producers. Onshore permits for oil and gas exploration and coal mining will continue. Any major political or economic shock will affect “transformation”, as Robertson warns.

In response to interest and concerns about the effect which oil industry development would have in the province of Newfoundland, a number of studies were initiated, including attempts to assess the impacts on rural residents. An analysis of the offshore labour force indicated that Newfoundland residents represented 60% of the offshore force; however, their participation was predominantly in the junior drilling, junior marine and junior service positions. The provincial workers differed from the non-resident workers on a number of factors. Also of interest, the 35% of the Newfoundland workers interviewed had come from water transport occupations and were attracted by the perceived advantages of work in the oil industry, while the 34% who had come from the fishing industry, cited financial insecurity and poor working conditions of the fishery as their reasons for changing jobs.

A proposal to undertake exploration in the coastal waters adjacent to Sydney/Newcastle/Wollongong has brought strong protests on environmental grounds. This opposition is committed and the basis for it should be considered in the wider context of offshore exploration around Australia. Of the various activities involved in oil and gas exploration the potential impacts of marine seismic surveys and the likelihood of a blowout- related oil spill are those of greatest concern to the media and public.A review of the available literature shows the environmental effects of seismic surveys to be of little consequence provided non- explosive energy sources are used. The effects of an oil spill are heavily dependent on site conditions and the type of oil spilled.The literature shows that direct exposure to spilled oil is fatal to many marine species. However, the potential lethal effects are largely dependent on direct exposure and this declines with the weathering and degradation of the spill. Moreover, the risks of an oil spill occurring as a result of current transportation and handling of oil in coastal waters and points around Australia are much greater than would be presented by drilling an exploratory well.In considering the role of exploration as an assessment procedure rather than a land use it is possible to draw parallels between the conservation status of Australian coastal waters today and the onshore situation some 20 years ago. The offshore oil and gas exploration industry needs to take several measures if it is to avoid denial of access for exploration. These include clearly identifying the environmental effects of exploration as opposed to production, adopting industry- wide codes for environmental practice, and recording and disseminating the industry's environmental performance.
