The Bunnings Workshop community can help with your home improvement projects.
It's great to have flowering plants in pots and your garden in springtime.
Consider varieties of violas and snapdragons.
Bunnings also has plenty of other annuals that will add a splash of colour to your garden.
Hanging some of the flowers could be effective, too.
You should find this step-by-step guide useful: How to create a hanging basket garden. - MitchellMc
Coming into summer, you could look at petunias, marigolds, dwarf zinnias, New Guinea impatiens, alyssum and bedding begonias for colour in pots.
For hanging baskets, trailing and cascading plants like calibrachoa (looks like miniature petunia flowers), lobelia, bacopa, Dichondra 'Silver Falls' and nasturtiums would be good in different colour combinations.
Have a look in Bunnings at baskets and pots already planted up for inspiration! - Noelle
I recommend having a look at this guide - How to build a tiered plant stand. This plant stand will allow you to use more of your space effectively, allowing you to have a wall of flowers. - EricL
