A bed manufacturer gave the following dimensions for mattresses in New Zealand. (These are likely to be the same as Australia.) Note that the bed itself will be larger and will vary according to the design. Dimensions are in mm.
Single 1880L x 915W
Long Single 1980L x 915W
King Single 1980L x 1070W
3/4 Double 1880L x 1370W
Long 3/4 Double 1980L x 1370W
Queen 1980L x 1525W
King 1980L x 1675W
Super King 1980L x 1830W
I have also heard of a California King which may be 1980L x 1980W.
There are many options of places to buy a queen-sized air bed. Local big box retailers would likely have the best selection as well as smaller furniture stores.
The general answer is that a queen bed tends to be a little bit wider and a little bit deeper (taller) than a full mattress. The length of the beds (head to toe) tends to be the same. However, the big difference usually comes in when buying sheets. While, for the most part, a queen sized sheet will fit a full sized bed and vice versa, different brands may have different sizing. If a brand sells only twin, a full/queen, and king sized sheets, you can safely assume that the full/queen will fit both a full and a queen. Some brands do break it down and sell both a full and a queen size. For these brands, you can probably get their queen size to fit your full bed, but you're likely to find the full size sheet to be too small for a queen sized bed.
as big as a single bed
You can get it for any sized bed.
They all vary to the inch, but the 'Queen' size bed is the largest of the Bed Family.
A super king sized bed is the largest bed size one can buy. In North America, the king-sized bed measures 76 inches by 80 inches, making it almost as wide as it is long.
The standard size of a queen bed is 152.4cm by 203.2cm. This is an average size for a mattress and can fit one or two people. Some couples would need to go up a size.
King.
A queen bed is big.. i think he would be the only one sleeping on it...

The soundtrack for the 2008 movie Queen Sized contained only two songs. They were Perfect World by Samantha Mollen and Big Girls Don't Cry by Fergie.
The queen comforter would be a tad big for the full bed, but it would not be noticeable except to the comfortable user. The queen size is only about 4 inches larger than the full bed in width and about 5 inches longer.
