The majority voted against a motion, which means that it was unsuccessful.
Greens Senator Rachel Siewert had proposed the motion to give full protection to five shark species that don't have that at the moment.
Wording of the motion
That the Senate—
(a) recognises that:
(i) sharks play an important role as apex predators in marine ecosystems, and
(ii) world shark populations are falling by between 63 to 273 million per year due to fisheries overexploitation;
(b) notes that the Australian Government has entered reservations against five shark species (big-eyed, pelagic and common thresher sharks, and scalloped and great hammerheads) under the Convention on the Conservation of Migratory Species of Wild Animals, removing those shark species from the full protection otherwise provided by the Environment Protection and Biodiversity Conservation Act 1999 (the Act); and
(c) calls on the Australian Government to remove reservations for those five shark species, and to provide them full protection under the Act, by continuing to list Appendices I and II species on the Convention on Migratory Species as 'migratory species' under the Act.
