Question about citizenship application - 'Other names' section and 'Debt' questions

[Sigemup 1]

Hi guys,

I have 2 questions about 2 sections in the citizenship application.

1. Other names: Questions that asks if I have any other names. In this the help button (question mark) explains that it can include if someone changed their name or have used preferred name etc. 

For this, I am not sure if my names are considered other names. I have a long name (both first name and second have 2 parts in each and are long) and sometimes for last name I use initials. For example: First name: John Last name: Thomas Wilson - for such a name I use John T W as my name in some documents whereas other documents use John Thomas Wilson. 

Could you please let me know if this would be considered as other names ? Because it is the same name but simply initialized.

2. Debt: After I submitted tax returns a couple of years ago, I had a medicare levy surcharge to be paid. However I forgot and missed the payment. Few months later I received a letter from probe collections. I immediately paid the amount and cleared it. 

For the question "Have you ever had a debt to the Australian government" - Should I say 'yes' or 'no' 

Thank you
