So i am covered if i put a waterblock onto the card by AU laws?

Yes, EVGA warranty covers you. With the following caveat :
All products must be returned in the originally sold condition. Products received by EVGA for replacement that include 3rd-party attachments (CPU heatsink backplate, memory chip heatsinks, etc) will have all attachments removed and discarded. EVGA holds the discretion to return the product to the sender if necessary.
 
There must be no physical damage to any component including the PCB, GPU/chipset, CPU Socket, or damage that is caused by:

• inadequate or improper repairs carried out by any person or entity which is not authorized by the manufacturer to perform warranty services on its behalf;
• negligence, accidents, modifications, defective installation or misuse and use of inappropriate spare parts;
• fire, immersion in liquid, lightning, earthquake, inadequate ventilation, Acts of God, incorrect application of main voltage howsoever arising, or any other cause beyond the control of EVGA;

In other words, if you install a waterblock, your warranty is intact for an RMA as long as you return the GPU in it's stock state and you didn't physically damage the GPU.
