The Pacific Highway (A1) and Pacific Motorway (M1) is a highway running between the Australian cities of Sydney and Brisbane, up the north coast of New South Wales.
The Pacific Highway is the major road link between Sydney and Brisbane. Additionally, it passes through a populous area of New South Wales, connecting you with many of the state's major cities and towns. The Pacific Highway is 800 km long. It is possible to drive up the highway in a single day, but this is a six-segment itinerary with several shorter drives and a number of stops in New South Wales cities.
When planning a trip up the Pacific Highway, the major consideration is holidays. The Pacific Highway links several large Australian cities and also passes through major beach holiday areas close to Sydney. Thus traffic is absolutely nightmarish at either end of a holiday period; it's not unheard of for trip times to be four times as long. The worst times to be traveling north are the afternoon and evening of Christmas Eve (or of the day before if Christmas Eve is a Sunday), the afternoon and evening of the day before the Good Friday holiday and the night before and morning of the first day of any long weekend. When traveling south, the end of holiday periods are the peak time. Since Australians take summer holidays in January, you will also want to avoid traveling north on the Friday or Saturday of any weekend in January, and likewise avoid traveling south on Sundays in January.
As the Pacific Highway is a major road passing through a populated area, there's no need to take special precautions as you might when driving through a remote area. It might be a good idea, as with all car trips, to make sure that you have food, water and warm enough clothing so that having to sleep in the car for a night wouldn't be a disaster. However, you will have ample opportunity to purchase all food and drink along the way.

You can start from either end of the road, or from many points along its length. To the south, Sydney is a major gateway, and to the north Brisbane and the Gold Coast both have many transport options. You can hire a car at either end, shop around for a good one way deal if you need one.
