Dear Mr Allegretto:

I spoke to Mr Adam Phippen on Friday 13 October and obtained his consent to our
filing this Letter of Response on Monday 16 October 2006.

Form 10-KSB for Year ended December 31, 2005
- --------------------------------------------
Item 7, Financial Statements, Page 15
- -------------------------------------
Consolidated Statements of Cash Flows, Page 22
- ----------------------------------------------

I attach an electronic copy of an Excel spreadsheet that details the Cash Flow
transactions for the Fiscal Year ended December 31, 2005.

I confirm that the Australian subsidiary receives all its funding from its US
Parent in USDollars. Because all these funds for the Australian subsidiary are
provided by the Parent company the translation amount in the cashflow is the
same as the translation gain or loss. (refer Table 1)

The Australian cash flows are compiled in accordance with SFAS 95. In the
interests of ease of understanding I have attached the Cash Flow statements for
December 2005 only. The schedule will provide you with the methodology that has
been used to compile the Filed cash flow analysis. If required by you we will
provide the comparable analysis for the March and June Quarters.



Table 1       AQUA DYNE, INC.
              EXPLANATION OF WHY THE
              COMPREHENSIVE GAIN (LOSS) ON TRANSLATION
              IS THE SAME AS ADJUSTMENT FOR FOREIGN CURRENCY TRANSLATION


Aqua Dyne, Inc. transfers U. S. dollars to its subsidiary in Australia to pay
all of the expenses of the subsidiary. Austrialian operation does not have any
other source of local financing.

Therefore, the effect of transactions in Australian dollars (AU$) is the same as
for the U. S. $ accounts.

EXAMPLE

Aqua Dyne, Inc. U. S. transfers $100,000 to Australia. Australia converts U.S. $
to AU$ at say .7000 AU$142,857

Australian company then incurs expenses for the period of say one year in the
amount of AU$ 120,000


     
The result would be the following
              Australian Company
              Balance sheet at end of year      AU$           US$          (assuming exchange rate is now 0.76

Cash                                           22,857        17,371        and average exchange rate is 0.73)

Total assets                                   22,857        17,371


Payable to Aqua Dyne, Inc.  U.S.              142,857       108,571


Loss for the year                            (120,000)      (87,600)

Comprehensive gain                                           (3,600)

Total liabilities and capital                  22,857        17,371


              Profit and loss for the year


Expenses                                       120,000       87,600


Loss for the year                             (120,000)     (87,600)


Assume that the rate during the year went form .7000 to .7600 with the average
being .7300. In accordance with translation principles the average rate would be
used to translate the profit and loss for the year into U.S. $

              Cash flow for the year


Net loss                                      (120,000)     (87,600)



Financing activity

              Loan from U.S parent             142,857      108,571


Comprehensive gain on translation                    -       (3,600)


Net increase (decrease) in cash                 22,857       17,371

As can be seen from the example the change in the Balance Sheet comprehensive
gain and the Cash Flow comprehensive gain on translation are the same.

Conclusion:
When all of the funds are provided to a foreign subsidiary, and the foreign
subsidiary does not provide any of its funds, the comprehensive gain or loss on
translation is the same for the Balance Sheet as the Cash Flow because it all
originates in U.S. $


Comprehensive gain pertaining to cash consists of (using formula per FAS 95):
              Cash ending balance

                         At yearend rate                  a  $17,371

other employees who have a significant role in the Registrant's internal control

3.       In June 2006 the company incurred costs associated with the provision
         of services by external parties. These costs were the subject of
         contractual arrangements. As the obligations did not fall due until 30
         June it was impossible to facilitate the issuance of the stock
         certificates by 30 June. The company accounted for the liability as an
         issuance of stock but with the proviso that the actual certificates did
         not issue until July 3. This approach meets the need to match expense
         and liabilities at the time of the obligation. The event only occurs
         when there is an obligation at the end of a quarter. The company
         understands that the accounts need to reflect the effect of the
         transaction. The anomaly occurs when the stock reconciliation is
         correlated to the accounts. If we were to provide a Note to the
         Accounts this may meet the SEC requirements.

In the event that the staff has any further requests or matters seeking
clarification, please feel free to contact our Company Secretary Mr Ian
Hutcheson at your earliest convenience on 61 7 3832 9883, fax 61 7 3832 1336.


Sincerely,
