  • Jarrrah (termite resistant)
  • Tallowwood (water resistant)
  • Ironbark (long lasting)
  • Stringybark (great compromise)
  • Spotted Gum (fire-resistant)
  • Merbau (affordable)

Step 4: Get all the right tools and supplies for the project


There is a large range of tools and supplies needed to complete this project. So it is a good idea to get a head start on obtaining all these before you start the project. 

The following tools and supplies will need to be acquired: 
  • Shovel
  • Chisel
  • Hand or powered saw
  • Screw Driver
  • Spanners
  • Measuring Tape
  • Hammer
  • Square
  • Builder’s Line
  • Electric Drill and Drill Bits
  • Adjustable Wrench
  • Spirit Level
  • Wooden and Metal Stakes
  • Spray paint
  • Glue
  • Nail Gun
  • Fastener

Step 5: Measure and mark out your deck


Since all the preparation is done for the deck, it is now time to start the measuring and marking of the area. To do this, you want to measure out all the points with taking note of the height of the deck and the joists. You can use sills to mark out the perimeter of the deck. After installing the sills into the soil, you want to use string cord to secure the height around the perimeter of the area.

Step 6: Install the stumps and bearers


Before installing the stumps and bearers you want to first outline the digging holes where the sills sat with spray paint. Once the holes are outlined with the spray paint you can move onto digging the wholes, with keeping in mind your set hole depth. It is recommended to consult with an inspector and get them to look at the holes before you start filling the holes. The next step will require you to install the stumps and the bearers. 

Step 7:  Install the joists 


With installing the joists you need to measure and markout the wall-plate. You will need to attach the wall-plate and once done you can attach the joist. As a precautionary, it is suggested to measure the first joist with the second just to make sure that your measurements are right. 

Step 8: Lay the decking


Now it's time to lay the decking, this is the fun part. Before you start laying you want to cut your timber down to the correct size. Once complete, one-by-one you need to lay a timber slab down and fasten it with drilling it into place. Repeat this process and you will have a complete deck! 

Step 9: Enjoy your new deck!


Most importantly, it is time to relax and enjoy your deck after all your hard work!
