I would suggest you start wherever you can get a parking spot and having the sun against your back would be the most pleasant way to do it if it's hot

It starts in the centre of Port Macquarie (Westport near Settlement City) and finishes up at Tacking Point. There are a number of sections so you don't need to do it all at once. It's a good idea to take water with you as it can be a thirsty walk depending on the weather. The walk can be divided into four sections: Westport to Town Beach (2km) Town Beach to Flynns Beach (2.2km) Flynns Beach to Shelly Beach (2.2km) Shelly Beach to Tacking Point (2.7km) You can also start the walk at Town Beach near the Breakwall, winding along the coast via Flagstaff, Rocky Beach lookout, Nobby’s Beach and Harry's lookout to Sea Acres. There are several historical sites along the way and from May to November you could quite possibly see whales on their migration. The walk ends at Tacking Point lighthouse; however you can break it up into shorter sections if you feel like a short walk or are walking with kids. There are opportunities for barbecues and swimming along the way, including at Shelley Beach and a beachside café at Flynn’s Beach that serves up gourmet burgers. You could also start the walk at Tacking Point; finishing up at the Royal Hotel in Port Macquarie.

I'd say not wheelchair accessible for a good portion of the walk. There are some steps, and although a good deal of the walk is sealed, there are parts that are not. Even the sealed parts a bit rough here and there

It depends on which way you walk. If you walk in to town from Lighthouse Beach there is a bus that goes to the lighthouse area. I'm not sure how often the bus runs though as it is a private bus service and may be infrequent. On weekends it will be very infrequent.

Probably not a good idea with a pram. It is quite steep in sections and sandy beaches. There are other nice walkways around Port that you can do with a pram. Be advised that the area is in for a deluge rain front over the coming days with flooding expected. A severe weather warning is in place for the whole eastern seaboard. It may be a good idea to check on conditions before heading there.

The only charge you may have is transport back to your vehicle. There are plenty of taxis and A$20 should easily cover the fare from one end to the other.
