How to remove existing lawn and lay new lawn?

[Sampath]

Hi, I am trying to replace my existing lawn with new seeds/lawn. Currently it's in a bad shape with weeds all over the place and cracked soil. Any ideas and tips to loosen the soil and replace the complete lawn with new. TIA

Hi @Sampath 

Your welcome to ask questions sorry that sometimes I forget or just assume everyone is very advanced at DIY thats on me. RE the  black plastic.

I will dial it down to include more people. Personally I am still learning today so I know how frustrating someone missing a step or minor bit of information can stop us in our tracks. 

As you progress feel free to check in  with more questions.

Take it easy, @Jewelleryrescue —I missed it earlier too. However, this community is really helpful. As @MitchellMc suggested, I got the black plastic from Bunnings. I'll apply the weed killer today and then place the plastic on top. I'll keep the project updates posted here.
