NSW has three blood alcohol limits:
Zero, 0.02 and 0.05.
These numbers refer to a person's blood
alcohol concentration (BAC).
BAC is a measure of the amount of
alcohol you have in your blood.
The measurement is the number of grams of
alcohol in 100 millilitres of blood.

How much can I drink
and keep below 0.05?
As a general guide:
For women: No more
than one standard drink
each hour, less for
smaller women.

The human body can
only process about one
standard drink per
hour, and alcohol
concentration does not
peak until 30 to 60
minutes after your
last drink.
As such somebody consuming large quantities of alcohol
can still be unfit to drive the next morning.

Body size
A smaller person will have a higher BAC than a larger person because the
alcohol is concentrated in a smaller body mass.
Empty stomach
Someone with an empty stomach will reach a higher BAC sooner than
someone who has just eaten a meal. Food in the stomach slows down the
rate at which alcohol passes into the bloodstream.
Body fat
People with a lot of body fat tend to have a higher BAC. Alcohol is not
absorbed into fatty tissue, so the alcohol is concentrated in a smaller body
mass.
Sex
After consuming the same amount of alcohol, a female will almost always
have a higher BAC than a male.
