Suggestions Welcome for new Trader

Hey Guys
Am a relatively new investor
Bit hyped on reading the posts from Anush & 8Horse on AVZ Shares
After careful consideration i have decided to invest in AVZ, SYA & PLS
Can anyone let me know what is the basic % one should divide the money into
I dont have more than 20,000AUD for invest this year
Appreciate the input
And i am not in a great need to remove that 20,000AUD for the next 10 years...
