I am trying to follow online instructions to do my garden edging with bricks. I will need to buy concrete to lay the base before laying bricks on top of it. I would like to know what concrete and brick mortar to buy before heading to Bunnings. Any advice will be greatly appreciated.

Yep - If your doing it one brick high just dig slightly below soil level, and put the brick straight on the ground.
If you want to get fancy a bit of weed matting (or cardboard) will help stop the grass from growing in the cracks, onto your garden beds
Thanks for the helpful advice. As the lawn area is raised from the ground, it'll need two bricks to go around it. I used Google Map to do a quick measure, the perimeter is about 25m. Based on this, is there a way to estimate the amount of concrete and mortar needed?
Will you still be pouring foundations for the bricks?
A rough guesstimate is one 20kg bag of mortar for approximately 25 bricks. From memory, it's printed on the bag.
Buy more just in case, Bunnings will take back the bags you don't use if they are unopened.
Yes, one part of it will need foundations for the bricks.
foundations for the bricks.
Use this calculator to work out how much concrete you'll need.
There are probably people who know better than me - but if you're using it to hold back soil and as a wall between two levels, sounds more like a small retaining wall than edging.
You might want to consider other design changes to make sure your wall doesn't slowly lean to one side due to moisture / weight.
buying bagged pre-mixed stuff will work out real expensive for long runs
Get concrete for the base, not mortar. It’s stronger.

If you have firm ground you may not even require a concrete base, lay the brick straight onto the ground if you are only going 1 brick high..
It could work out very expensive for a decent thickness concrete base.
It may pay to look into mini mix concrete, depending on how large your area is.
If you have a trailer consider buying a sand/aggy mix and a bag of cement and mixing your own. It'll be a lot cheaper
For your brickwork, you'll need a mortar mix.

If laying bricks straight onto the ground and end to end you may not need any mortar.
