Plugs and sockets that conform with the AS/NZS 3112 standard are used in Australia and New Zealand and several Pacific Islands, which explains the name Australasian type. Comparable plugs are used in China, Argentina and Uruguay.
Origin of the type of plug is described on a separare page.

Standard domestic 10A type-I socket Type-I 10A plug Australian 250V - 10A dual power outlet Australasian 10A vertical dual socket

1, 2
Standard domestic 10A - 250V socket and plug. Power pins (N and A; A means Active = line) and corresponding slots are obliquely positioned and resemble an inverted 'V'. The position of the pins makes Australasian type plugs irreversible. Even a not earthed, 2-pin plug is polarized.

Standard domestic rewirable plugs always have 3 pins, but the earth pin may be omitted on plugs moulded on appliance cords using IEC type C1 or C7 connector, as used for low current double insulated devices - such as battery chargers or shavers.
(image no. 26 on the page about IEC 60320 appliance couplers shows an example).

The earth pin is longer than the angled power pins and makes contact first. From April 2005 partially insulated power pins are mandatory for all plugs. Standard domestic plugs sold in Australia and New Zealand have a side entry cable. These plugs extend much less outwards beyond a wall socket than a top entry plug. Moreover, they are safer because it is not possible to pull out a plug by pulling the cable, rather than the plug.
Note that the cable entry is never positioned
straight downwards (180), but in a 135 rotated position (see insetbottom right). This allows the use of two or more side entry plugs below each other (for example in dual socket no. 4).

Manufacturers: PDL (no. 1), and Elto, New Zealand (no. 2). Brand logos and deatail are given below.
3, 4
A horizontally mounted dual socket (no. 3) is the preferred model in Australian and New Zealand homes, but dual sockets with outlets on top of each other are available (no. 4). Manufacturer: Clipsal.   {PT}

The choice between a horizontal and vertical dual flush socket is quite unique. U.S. flat blade and European Schuko dual sockets are always 'vertical', whereas British BS 546 and 1363 dual sockets are 'horizontal'.

9, 10 Rewirable 10A plug with a single outlet, officially a "socket adapter plug", but commonly known as 'Piggy-back' plug (no. 9). The rewireable form of this plug is now banned from sale in Australia, but it is still available in New Zealand - where it is also known as a 'Tap-on' plug. In Australia this plug/outlet combination is available only when moulded onto an approved extension lead (no. 10).   {PT}
Manufacturers: PDL, New Zealand (no. 9) and Arlec Australia Pty Ltd, but made in China (no. 10).
